Product introduction

Salinity meter is an online intelligent salinity meter independently developed by our company. High performance CPU chip and SMT patch technology are used to measure salinity and temperature and to compensate temperature. It can be widely used in continuous monitoring of salinity value of pyroelectricity chemical fertilizer metallurgy environmental protection pharmaceutical biochemical food and tap water solutions.

 Main features

• Large screen lattice LCD display Chinese menu operation.
• Bromine can be used to measure salinity and control upper and lower limits.
• Alarm status is displayed ON the screen and can be accompanied by ON/OFF signal output.
• Automatic temperature compensation function: 0~100℃.
• Communication unction (optional) RS-485 communication interface (MODBUS protocol partial compatibility) the corresponding salinity value of 4-20mA current output can be set arbitrarily.
• Watchdog function: make sure the meter doesn't crash.
• Restore factory Settings function. Power off protects > 10 years.
