HR8801 water level temperature monitoring recorder-HighReach

HR8801 water level temperature monitoring recorder

HR8801 Water level and temperature recorder is a groundwater monitoring instrument which can be either external powered or internal battery self-powered it is used for the long-term recording of the depth (pressure) and the temperature. The transmitter contains the water level and temperature sensor built-in large capacity non-volatile memory and high capacity long-life lithium battery it ‘s entire stainless steel structure enables all functions are integrated inside a metal casing it applies to measure the surface water groundwater as well as the water level of marine environment.

Dry capacitive ceramic sensor

Nice stability on long-term service

High precision up to 0.05% F.S

Strong overload capability preservative

Full temperature compensation full scale digital calibration

RS485 standard MODBUS-RTU protocol can be used in DCS or PLC systems
