pH meter HANNA HI 99141 (pocket)
pH meter HANNA HI 99141 (pocket) A durable, waterproof and portable pH and temperature meter designed specifically for use in boiler rooms and cooling towers. In the device The pH electrode HI 72911D with signal amplification and double diaphragm is used, characterized by an easy-to-clean flat sensing element, which prevents its contamination by solid deposits from solutions. The titanium body of the HI 72911D electrode functions as a potential matching contact, which improves measurement stability and extends life services. The titanium housing also provides an unbreakable design and allows heat to be transferred to an internal temperature sensor for rapid temperature compensation. Features: Automatic temperature compensation. Automatic one or two point calibration. Waterproof design. BEPS (Battery Error Prevention System) – Alerts the user when the battery level is low, which may adversely affect the readings. Compact, ultra-durable. Shows the battery charge level in % at startup. HELP function displays educational messages on the LCD display. Manba: https://www.nv-lab.ru/catalog_info.php?ID=2748
