ESMPHA-1000 PH/ORP meter for acidity alkalinity or oxidation-reduction potential
PRODUCT DESCRIPTION
ESMPHA-1000 pH meter determines the acidity or alkalinity (pH value) of a solution by detecting the potential difference of the electrode and converting it using the Nernst equation.
Product Features
- LCD display with Chinese menu operation, stable performance, and high reliability
- High-performance operational amplifier, ORP positive and negative electrodes symmetric, low drift, high accuracy
- Data is not lost after power off
- Dual 4-20mA transmitter output, relay high and low alarm control output, RS485 communication output
- Simultaneously displays pH value, temperature, output current, high alarm value, and low alarm value
