Battery life is more than 1500 hours and the percentage of the remaining charge is displayed when the meter is turned on. HI 99171 turns off automatically after 8 minutes of inactivity.

HI 99163 - Meat pH Meter

HI 99163 is a specific instrument for the pH analysis of meat products. The specially designed electrode FC 232D incorporates many essential features to perform reliably without damaging the sample. This probe has a built-in temperature sensor that provides automatic temperature compensation, an open junction to avoid a clogged reference and its external body material isn't toxic. The probe body has an external thread to securely screw on the stainless steel penetration blade FC 099, included in the kit. The replaceable penetration blade allows the user to measure not only the surface, but also the internal pH of the meat. This pH meter is simple to use with only 2 buttons. All necessary information is clearly displayed on the LCD. Besides displaying pH and temperature, the LCD of the HI 99163 also indicates the reading stability, as well as the remaining battery charge. Calibration is automatic at 1 or 2 points, selectable between 2 memorized buffer sets. Battery life is more than 1500 hours and the instrument automatically turns off after 8 minutes of inactivity.

HI 99161 - Waterproof Portable pH Meter for Dairy Products

HI 99161’s waterproof casing provides excellent protection from water and humidity, typically present in the food industry. HI 99161 is supplied with the FC 202D pH electrode with built-in temperature sensor, specially designed for use in the food sector. This electrode features a rugged, easy to clean, Kynar® body that tapers to a strong conic tip ideal for measurements in semisolids such as meats and cheeses. The electrode has a free diffusion sleeve type reference junction which prevents the typical problems of clogging in viscous liquids or samples with high solids content such as milk or condiments. The electrolyte used in the FC 202D electrode is free from the poisonous silver chloride, which prevents food contamination by the electrode. HI 99161 allows automatic calibration at either NIST or standard buffer sets with auto recognition and a stability indicator. The temperature is continuously displayed on the secondary level of the large LCD. The meter runs on common 1.5 AA type batteries and the LCD provides a low battery warning signal.

HI 99141 - Waterproof pH Meter for Boilers and Cooling Towers

pH/temperature meter, specifically designed for boiler & cooling tower applications. HI 72911 double-junction pH electrode (included) has an unbreakable titanium body and a flat tip. The electrode also features an annular Teflon® junction for maximum surface contact, giving increased response and stability. The titanium cage of the probe functions as a shield and adds to the sensor’s life. The flat tip is easy to clean and prevents solids in solution from collecting on the sensor.

HI 99121 - Kit for Direct Soil pH Measurement with Special Electrode

The HI 99121 kit has been designed to address the question of correct and rapid measurement of pH directly in soil. Every item in this kit has been made to facilitate measurements in the field without compromising accuracy. With HI 99121 you can test the pH of soil directly or after preparation of a diluted sample. In order to measure the pH directly, the kit includes a plastic auger to perforate the ground. The HI 1292D pH electrode has been
designed for direct soil measurement. It has a conic, rugged tip and can be directly inserted in moist or soft soil. The electrode incorporates a temperature sensor right near the tip to enable it to measure and compensate for the temperature quickly. For higher degrees of accuracy, or for stony ground where the electrode may be damaged, use the specially made HI 7051M soil preparation solution. This solution is included in the package to help you measure pH more precisely by diluting a sample of the soil in it. The dual-level LCD shows the pH value from -2 to 16 with 0.01 resolution. It also displays the temperature on the secondary level at the same time. With a menu-driven custom microprocessor, the user is helped with clear prompts during operation and calibration.
