hydroCHEM Conductivity and pH Controller
|
|
Full Size Image |
 | 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. |
