hydroCHEM
  • Automatic controller for Conductivity and pH. Ideal for Hydroponic applications. Designed to control external pumps, valves etc. Temperature readout is provided. Supplied with sensors and calibration standards.
  • The new advanced design makes this unit far superior and yet cheaper and easier to use than other brands. The hydroCHEM is the culmination of over 30 years manufacturing experience.
  • Waterproof construction rated to IP65.
  • Supplied with 24V DC output control cable for low-powered devices or relay etc.
  • Memory for 2300 stored readings, with automatic datalogging facility (optional).
  • RS232 Interface for remote monitoring of system (optional).
  • Pump sensor only allows automatic dosing when circulating pump is on.
  • Large digit mode makes the data easy to read in any light or from a distance.
  • Automatic calibration
  • 4 Terminal conductivity sensor technology resists fouling for maximum reliability.
  • User can choose readout in mS/cm, CF units, dS/M or ppM (TDS).
  • Quick-dose function
  • Temperature readout with optional temperature control output.
  • Fully adjustable ON and OFF times can be set separately for Conductivity and pH pumps, eliminating over-dosing.
  • User can select acid or alkali addition.
  • Password protection, so only qualified users can change set-up or calibration.
  • Good laboratory practices (GLP) function brings analytical Q.A. to the hydroponics farmer. Instant recall of current calibration and system set-up information.
  • 24 Hour calendar clock (optional).
  • Emergency shutoff timer shuts off Conductivity and pH pumps if they operate continuously for user-set time.
  • Operates off a single AC/DC power supply. No electrical installation required.
