Product Description

Intelligent water hardness meter is widely used in water plants, power plants, boiler water etc. It is designed for continuous detection of hardness value in liquid.

Main Features

◇Advanced water hardness ion-selective electrode technology (ISE) with high sensitivity, fast responsibility and stability. Easy to care and maintain.

◇IP Grade：IP65 (waterproof, dust-proof and damp-proof).

◇Digital LCD display and Chinese/English display interface.

◇Multi-parameters showed at the same time:

Water hardness value, temperature, output current, and alert of range ability etc.

◇Able to restore factory settings.

◇Automatic / hand-operated temperature compensation function.

◇(Optional) Communicating function：with RS – 485 communication interface (MODBUS protocol compatible) .The corresponding hardness data of 4 ~ 20 mA can be set freely.

◇Optoelectronic isolation ( output current: 4～20mA)

◇The retardation can be set freely to avoid frequent operation of relay.

◇Watchdog：make sure the meter won’t go dead.

◇The main units come from foreign famous brands.

◇Power down protection＞10 years.

◇ABS plastic casing (waterproof, dust-proof and damp-proof).

Technical Parameters

◇Range of measurement：

Water hardness  0-10000 mg/L（ppm）

Temperature  0~60℃

◇Selective units: mg/L,mmol/L

mmol/L(Boiler) =mmol/L(B) (Specified unit for industrial boiler water)

◇Resolution: 0.01mg/L, 0.1℃
