HI99141 /HANNA/WATER PROOF METER/FOR BOILER &COOLING

รายละเอียดสินค้า

HI 99141 is a waterproof, portable pH and temperature meter, specifically designed for boiler and cooling tower applications. HI 72911 double-junction pH electrode (included) has an unbreakable titanium body and a flat tip and features an annular Teflon® junction for maximum surface contact which provides increased response and stability. The probe's titanium sheathing functions as a shield and adds to the sensor's life. The flat tip sensor is easy to clean and prevents solids in solutions from collecting on the sensor. This advanced electrode also contains an integral temperature sensor and a mini amplifier to boost the electrode signal, eliminating the effects of noise and interference. The meter reads from -2 to 16 pH, while simultaneously showing the temperature in °C or °F. Graphic icons guide operations. An instability indicator with hold feature determines when to freeze the reading for easy record keeping. Calibration is performed automatically at one or two points with standard or NIST calibration buffers. Battery life is over 1500 hours and at startup, the LCD shows the remaining battery power. In addition, BEPS (Battery Error Prevention System) prevents bad readings due to low voltage and an auto-off period at 8 minutes saves battery power.
