The HI98120 ORP/Temperature Tester is a waterproof and floating handheld meter designed for accurate ORP (redox) and temperature measurements in water. It is well suited for monitoring chlorine levels via ORP in swimming pools, spas and other non-industrial applications. The fully sealed housing protects the tester against moisture, making it reliable for regular field use.
The stainless steel temperature probe provides fast and accurate temperature readings. The tester features Hanna’s replaceable ORP cartridge electrode with a stainless steel connector, eliminating fragile pins during replacement. A dual-level LCD displays measurement results clearly, along with battery status in percentage and a stability indicator.
