837-1 Digital Salinity Salt Water Quality Meter Tester Checker Water Pool and Koi Fish Pond, Hydroponics, Gardening, Aquariums with Temperature 70ppt Water Quality Tester IP65 Waterproof Rate


Model : 837-1

Dual meter is designed to measure the salt content in liquid without the need for conversions. It measures both temperature (ºC/°F) and salinity (ppt) and display simultaneously on its clear LCD. It has an IP65 Rating, splash proof and dust proof housing and splash proof membrane keypad.

Applications & Usage:

It quickly and accurately measure salt concentration in koi ponds. Salt deters algae growth, detoxifies nitrite, and eliminates fish parasites and bacterial infections. Ideal for checking salt in fish hospital tanks and tropical aquariums, water monitoring, seawater-prepared food solutions, breeding ponds, aquariums, holding tanks and more!

All push-button calibration & operation and intended for outdoor or indoor use.
