Fixed site water sampler in stainless steel housing with thermostatic control for automatic sample extraction according to the vacuum principle. Mains operation 230V/50Hz.
Housing Double-walled stainless steel (material 1.4301) with 40 mm insulation. Consisting of upper part (control unit) and lower part (sample compartment), each with lockable door. Upper door with plexiglass window. Protective top which can be opened for connection and maintenance works.
Thermostatic control Self-contained, automatic cooling and heating of the sample compartment to +4°C independent of the programmable controller, with protection against overheating and automatic defrost cycle.
Control Microprocessor control with 4 MB Flashrom, 32KB RAM (battery-buffered), 32 KB EEprom, 3 digital inputs and 8 digital outputs, 1 configurable analogue input, battery-buffered real-time clock. Operation by means of a waterproof foil keyboard (with keys 0-9, ESC, ENT, cursor) and 4 x 20 character back lit LC-display.
Language Multi-language, selectable
Programming Time display: Hours, minutes, seconds

weekday, day, month, year

Sampling: - Time-related

- Flow-related analogue (0/4-20mA) or digital

Option: flow-proportional

- Event-related or in combination

Interval: 1 min to 15 h

Bottle filling: 1 min to 99 h 59 min

Programs: 6 user programs (for free editing)

Data memory: Logging of sample extraction

and messages.

Optional storage of external data

Interface Optional: RS 232 (internal on CPU board in plug-in version, not led to the outside).
Modem Optional: GSM, AT or ISDN modem to change the programming, for a status fetch, a data fetch or a message transmission as SMS.
PC software Optional: PC software (Win98, NT, XP) for parameterization, status

control, data fetch and direct storage as excel file/text file/PDF

file.
Status messages Optional: Sampling, distributor, program active and collective malfunction

message by means of potential-free make contacts. Can be

extended to up to 10 outputs.

In addition, the desired messages (configurable by means of the software) can be transmitted via modem as SMS or text.


Overvoltage protection All inputs are protected against overvoltage (lightning protection).
Dosing system The following variants are available
