JENCO INSTRUMENTS was established more than 40 years ago on the idea that innovative water quality instruments should be available at competitive prices and their mission is to bring innovation to anyone who works with analytical instruments.

Since the launching of the world's first portable digital pH meter in 1975, Jenco Instruments has continued to focus only on building water quality instruments for measuring pH, ORP, conductivity, TDS, salinity, resistivity, dissolved oxygen, ion, turbidity and temperature. 

This single minded-focus is combined with Jenco's obsession with finding the best balance between quality and value - whether it is the simplest testers or the most advanced, gesture-operated, WIFI-enabled benchtop meters.

pH/Temp Industrial Online Controller

6312PTB


pH/Temp Industrial Online Controller



Details


 Features :

  • Graphic LCD with manual backlight displays pH, temperature, relay status, and transmitter current mA output
  • Automatic buffer recognition of US and NIST buffer sets. Calibration data is stored in memory and is ready for use on power up
  • Two sets of isolated and reversible 4-20 mA current output for pH and temperature allows it to be used as a proportional output
  • 4 programmable on/off relays: 3 for pH and 1 for temperature
  • RS-485 output for remote access allows multiple units to be connected and ganged together
  • Password protection
  • IP65
