Test Table

Simultaneous display of multiple parameters: It can simultaneously display pH value, temperature value, high point alarm setting value, low point alarm setting value, whether the instrument is in high or low alarm state, and the current time. All parameters are clear at a glance.

The unique 4-20 mA current output corresponds to a pH value that is reversible and can be set to any value, providing users with greater convenience.

useWaterproof and airtight fully sealed shell, more suitable for use in extremely harsh environmental conditionsThe protection level reaches IP65.

rs485 communication(Optional); Automatic cleaning function(Optional)

The unique design of the operation menu brings great convenience to users, and they can use it freely without reading the manual.

Three minute automatic backlight shutdown without button operation not only saves energy but also extends its service life; The screen contrast level is adjustable.
