Specifications are subject to change without notice.
Width 61 cm (24 in.), Depth 61 cm (24 in.), Height 110 cm (43.5 in.), Weight 63.3 kg (140 lb)
Fiberglass reinforced plastic with beige UV inhibited polymer laminate.
-29 to +50 °C (-20 to 122 °F); With optional controller compartment heater, -40 to +50 °C
(-40 to 122 °F).
With door open one minute in 24 °C (75 °F) ambient and 4 °C sample temperature, 5
minutes.
From 24 °C (75 °F) to 4 °C (39 °F), 15 minutes.
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.
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.
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).
Two C cell alkaline batteries; maintains program logic and real time clock for five years.
Internal battery current draws less than 40 micro amps.
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.
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.
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)".
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.
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.
Controller: 5 amp dc line fuse. Compressor: Thermal overload relay opens at
110 °C (230 °F).
Tests keypad, display, ROM, pump, liquid sensors, velocity signal, and distributor.
Access code protection precludes tampering.
Via RS232. Permits embedded software upgrades in the field.
RS232 compatible; allows on-site collection of stored data.
14400, V.32 bis, V.42, MNP2-4 error correction. V.42 bis MNP5 data compression.
MNP10-EC Cellular Protocol.
Alarm codes sent to up to three separate pagers' telephone numbers.
