Hanna Mini Liquid Level Controllers

Product Description


 

Accurate level control is critical to many industrial applications, especially for process adjustments using aggressive chemicals. Our sensor bars are built with stainless steel for long life even in harsh conditions. They are easy to install and ideal for monitoring tanks and water conditioning plants.

HI 7871 features high and low level control. HI 7873 includes an overflow alarm. The HI 7874 transmitter has been designed to be combined with the HI 7871 and HI 7873 level controllers. The transmitter is housed in a durable and waterproof ABS body, and allows the user to easily adjust the length of the sensor bars according to the specific need.
