Measuring pH in shampoo

Published 18. December 2015

Shampoo is a hair care product used for removal of dirt, dandruff, skin particles, oils and other contaminated particles.

As the scientists behind hair care progressed, manufacturers synthesized chemical additives for use in shampoo as fragrance, foaming agents, and colored dyes. Shampoo is now created and structured towards various hair types, as well as to achieve a certain end result, such as the reduction of dandruff or greasy hair. Both the synthetic and natural ingredients used in a shampoo dictate the pH of that particular product. The pH of a shampoo will alter the natural pH of skin and hair, which ideally falls between pH 3 and 5 and pH 4 and 5, respectively, thereby affecting their physical and chemical makeup.

Testers, monitors in Checker HC series

Tester

In the past, the measurement and monitoring of many important parameters was limited to the laboratory. Now, these parameters are being tested right in the field in various applications, including environmental study, agriculture, the food industry, horticulture, wastewater management, fish farming, water quality maintainence and anywhere quality and accuracy is important. 

HANNA has developed a large variety of testers and monitors designed to fulfill the requirements of virtually any application.

HANNA offers a vast selection of single and multiparameter testers which cover a multitude of the most important parameters: pH, ORP, conductivity, TDS, temperature, sodium, salt and relative humidity.

Testers can perform on the spot measurement quickly, accurately and inexpensively. They allow users with different backgrounds and technical training to make readings without the need of a laboratory, and without having to purchase much more expensive and complicated analytical equipment.

These testers have easy to read LCD’s and durable outer casings. They are able to measure in places with a high percentage of humidity, and low power demand allows a long battery life— no worrying about frequent battery replacement.

we'll be glad to help you find the right solution for your needs.

pH Testers

pH tester

All HANNA pH testers come with a replaceable pH probe, a huge advantage over most pH testers on the market today.

Clogged electrode junctions are a problem of the past with extendable cloth junctions. When the cloth is dirty from routine testing, readings become slow and instable. This is quickly fixed by simply pulling out 3 mm of cloth, and cutting off the dirty cloth.

Testers feature Automatic Temperature Compensation (ATC) and calibration at one or two points. Being pocket sized, with a narrow tip, they are ideal for measurements in small samples or test tubes.

Conductivity testers                                                                                                                               HI 98103

EC Grocheck

Conductivity testers are widely used for monitoring EC/TDS in water conditioning, reverse osmosis, cooling towers, drinking water, wastewater, laboratories, agriculture, aquaculture and aquariums, hydroponics and printing industry. With EC/TDS selectable or fixed conversion factors, readings are made easy. HANNA conductivity testers feature an amperometric graphite conductivity probe that provides greater accuracy and repeatability in measurements because it cannot be contaminated by salt deposits in solutions. Calibration of conductivity testers is simple and it can be manually or automatically in a single point.

EC tester

Measurements are automatically temperature compensated to ensure correct readings.

                                                                                                                                     HI 98331

 

Salt and water purity testers

Salintest

The Salintest can help you monitor the concentration of sodium chloride in live fish storage tanks, tropical fish aquariums and oceanographic investigations. Measurements are performed conductivimetrically, with one point check in a standard salt solution.

Water purity testers enable users to check the purity of your distilled or demineralized water in environments such as printed circuit board washing, laundry, steam cleaning, and all areas where pure water is used. Measurement is conductivimetric.

 Hygrocheck



RH Measuring testers

Relative humidity testers from HANNA use the thin film polimer capacitance sensing method, assuring a quick and accurate reading. Readings are converted directly in RH units, meaning there is no need for estimating, charts, thermometers and no complicated calculations.

Thermometers

Term tester

HANNA's thermometers are provided with a unique CAL CHECK™ function for accurate measurements every time. HANNA temperature tester sensors allow users to take measurements with extremely high accuracy in a very short amount of time. The sharp tip of the probes can easily penetrate semisolid products, making routine controls simple and quick. These testers are ideal meters for measuring temperature according to HACCP requirements.

 

HANNA Monitors

Monitor 1

HANNA monitors and indicators are an ideal economical solution in applications where constant monitoring of a stationary sample is required. HANNA offers a large selection of wall-mountable monitors that cover a multitude of parameters allowing the user to choose the meter and probe that best fits their application. The multiparameter models allow the user to monitor up to three different parameters with one indicator.

Each monitor has been designed to meet specific application requirements such as in hydroponics, greenhouses, horticultural, water treatment, food preparation and processing.

                                                                                                                                      HI 981504

At startup, indicators perform a self check to assure proper working condition. Stability indicators and HOLD functions let the user know when to take readings and freeze the readings on display for easy and accurate recording. Selected instruments in this line provide a visual alarm so the user can easily recognize if the monitored solution is out of specification for the application.

Temp monitor

HANNA offers indicators with large backlit LCDs to give users instantaneous readings of both pH and temperature or EC and temperature with utmost clarity. Monitors are provided with automatic calibration, automatic buffer selection and automatic

temperature compensation features.

            HI 147

HANNA's wall mounted indicators are very easy to install and work with a 12 V power supply. Many models feature interchangeable probes, so that if an application requires a particular probe it can be plugged in to the meter. All monitors have durable outer casings protecting them from high humidity environments and rain.

Checker HC series

CheckerHC 1 

The HANNA Checkers® HC bridges the gap between simple chemical test kits and professional instrumentation. Chemical test kits are not very accurate and only give 5 to 10 points resolution while professional instrumentation can cost hundreds of dollars and can be time consuming to calibrate and maintain. The Checker®HC is both accurate and affordable.

The contoured style of the Checker® HC fits in your palm and pocket perfectly and the large LCD is easy to read. The auto shut-off feature assures the battery life will not be drained if you forget to turn it off.

  • Easier to use and more accurate than chemical test kits

High accuracy

Large, easy to read digits
