Specifications are subject to change without notice.
General
Dimensions
Width 61 cm (24 in.), Depth 61 cm (24 in.), Height 110 cm (43.5 in.), Weight 63.3 kg (140 lb)
Cabinet
Fiberglass reinforced plastic with beige UV inhibited polymer laminate.
Temperature Range
-29 to +50 °C (-20 to 122 °F); With optional controller compartment heater, -40 to +50 °C 
(-40 to 122 °F).
Recovery Time
With door open one minute in 24 °C (75 °F) ambient and 4 °C sample temperature, 5 
minutes.
Pull-Down Time
From 24 °C (75 °F) to 4 °C (39 °F), 15 minutes.
Thermal System
Top mounted compressor/condenser with fan forced air cooled condenser; three-sided 
wrap-around evaporator plate; 2 in. rigid foam insulation; microprocessor controlled 
thermostat maintains sample liquid at 4 °C (±1 °C); frost free; compression gasket door seal; 
refrigeration components and plumbing are corrosion protected with conformal coating.
Power Requirements
115 V ac, 60 Hz (230 and 100 V ac optional); Compressor Running Amperage 1.5–2.0 A. 
Locked rotor current 12 amps. Installation Category II.
Optional ac 
Power Backup
(Pump Controller Only)
Pump/Controller Only: Rechargeable 6 amp-hour gel lead acid battery takes over 
automatically with ac line power failure. Integral trickle charger maintains battery at full 
charge (factory installed option).
Internal Battery 
Two C cell alkaline batteries; maintains program logic and real time clock for five years. 
Internal battery current draws less than 40 micro amps.
Control Panel 
21 key membrane switch keypad with 4 multiple function soft keys; 8 line x 40 character 
alphanumeric, back lit liquid crystal graphics display. Self prompting/menu driven program.
Data Logging
Records program start time and date, stores up to 400 sample collection times/dates, all 
program entries, operational status including number of minutes or pulses to next sample, 
bottle number, number of samples collected, number remaining, sample identification 
number, and all logged data (i.e. level, flow, pH, stream temperature, refrigerated 
compartment sample temperature, ORP, rainfall, and any externally logged data - up to 7 
external channels). Also, up to 200 events are logged, including alarm conditions, program 
run/stop events, etc.
Set Point Sample Trigger
When equipped with integral flow meter, pH/temperature/ORP meter, conductivity, and/or 
D.O. monitoring options, sampling can be triggered upon an upset condition when field 
selectable limits are exceeded. Concurrent with normal sampling routine, sample liquid is 
deposited in designated “trouble bottle(s)”.
Sampling Modes
Multiple Bottle Time, Multiple Bottle Flow, Composite Multiple Bottle Time, Composite 
Multiple Bottle Flow, Composite Time, Composite Flow, Flow with Time Override, Variable 
Interval, Start/Stop, and Level Actuation.
Program Delay
Three formats: (1) 1-9,999 minutes or flow pulses in one unit increments (2) programmable 
sampler start time/date, and (3) programmable time/day of week.
Overload Protection
Controller: 5 amp dc line fuse. Compressor: Thermal overload relay opens at 
110 °C (230 °F).
Diagnostics
Tests keypad, display, ROM, pump, liquid sensors, velocity signal, and distributor.
Program Lock
Access code protection precludes tampering.
Communications
EPROM Flash Memory
Via RS232. Permits embedded software upgrades in the field.
Serial Interface
RS232 compatible; allows on-site collection of stored data. 
Modem (optional)
14400, V.32 bis, V.42, MNP2-4 error correction. V.42 bis MNP5 data compression. 
MNP10-EC Cellular Protocol.
Pager
Alarm codes sent to up to three separate pagers’ telephone numbers.
