HI 504920 Remote User Interface pH Meter is a portable pH/ORP/temperature meter for use primarily with Hanna HI 504910 Digital Transmitter for two different applications: it can be a reference pH meter for calibrating the HI 504910 Digital Transmitter, or it can be set as user interface for the HI 504910 as well. All pH measurements are automatically compensated for temperature (ATC). The instrument housing is made of rugged, lightweight material, making it truly portable. Five memorized buffers (4.01, 6.86, 7.01, 9.18 and 10.01 pH) and wrong buffer recognition technology make calibration simple and error free. One or two-point calibration can be performed. An user friendly menu navigation makes operation easy. The large backlit LCD provides clear, easy-to-read readings.
The Hanna Instruments HI 504920 is a complete portable pH/ORP/temperature meter designed to be used with the HI 504910 Digital Transmitter. It features an automatic temperature compensation (ATC) system, five memorized buffers for calibration, and a rugged IP67-rated housing suitable for harsh industrial conditions.
The device allows users to perform one or two-point calibrations using pH buffers such as 4.01, 6.86, 7.01, 9.18, and 10.07. It includes a Battery Error Preventing System (BEPS) that warns of low battery levels while continuing to measure correctly until the batteries are too weak. The meter can be powered by four AA batteries or an external 12 VDC adapter.
