HACCP compatible high-functional residual chlorine concentration meter GRF-30-27A/40/45/43ht/45HT monitor
IWAKI CO., LTD.
About This Product
■ Features of GRF-30-27A
・ Continuous measurement of high -concentration residual chlorine with non -poroscopic chlorine water and sodium hypochlorate.
-There is an overflow type adoption to provide a certain amount of water to the sensor even if the amount of water is unstable, and stable measurement is possible.
■ Features of GRF-30-40/45/43HT/45HT
・ This is a device that continuously measuring the remaining chlorine of high concentrations with no -psychosal water and sodium hypochlorite.
・ Overflow type flow cells can provide a certain amount of water to the sensor even if the sample is captured and the amount of water is unstable, and stable measurements can be performed.
■ Standards, small flow, high temperature, high temperature & small flow type
・ GRF-30-40 Sample water flow volume: within 1.3L/min ± 20%, water inspection temperature range: 0 to 45 ° C (freezing)
・ GRF-30-45 Sample water flow volume: 0.2L/min ± 10%or less, water inspection temperature range: 0 to 45 ° C (freezing)
・ GRF-30-43HT Sample water flow volume: 1.3L/min ± 20%or less, water inspection temperature range: 35 to 75 ° C (within temperature compensation range)
・ GRF-30-45HT Sample water flow volume: 0.2L/min ± 10%or less, water inspection temperature range: 35 to 75 ° C (within temperature compensation range)
■ Equipped with data logger function
Equipped with a data logger function using SDHC/SD card. Logging is ① Remaining chlorine concentration (1 point) ② 4 ~ 20mA external import (1 point) is possible.
■ Full scale change is possible
The full scale can be: ~ 50 mg/L ~ 300mg/L by the sensor selection.
■ Pulse proportional control function
There is a pulse proportional control function using an electromagnetic quantity pump.
