Specifications
*In some industrial environments, radio frequency interference on the AC power line in the
30–50 MHz range could cause the refrigerator temperature to shift by up to 1.3 ºC. If
necessary, the user may adjust the set point temperature within the 2–10 ºC range to
compensate for such an effect.
Sample distribution Composite, samples per bottle or bottles per sample.
Setpoint sampling
Ability to start and/or stop a sample program based on an external trigger or
user-defined high/low setpoints based on SDI-12 measurements.
User start/stop times Up to 12 user-defined start/stop times/dates, with option to restart at position 1.
Storm water program Ability to run time-based, first flush program in parallel with main sample program.
Current status
Display parameters relevant to main and/or storm water programs and SDI-12
measurements.
Units of measure Volume: gallons or mL; length: feet (ft) or cm
Sample retries
Option to repeat sample collection cycle from 1 to 3 times if sample not obtained
on initial attempt.
Manual grab sample Ability to manually deliver a grab sample to a specific bottle location
Run modes Continuous or non-continuous with user-entered number of samples.
Time pacing Uniform or variable time intervals.
Flow pacing Uniform or variable flow intervals.
Auxiliary connector
Power to Sigma 9XX, SD900, flow pulse input, external inhibit, special output,
bottle number output and program complete output.
Program delay
Two formats: 1) 1–9,999 flow pulses (in one unit increments); 2) Programmable
start time/date
Timed Bottle Sets Enables a single sampler to function like multiple samplers.
Communication
Firmware updates Ability to perform field upgrades using Sample View software
Serial interface
RS232 compatible; allows on-site collection of stored data including event log and
sample history. Ability to configure remotely. Supports Modbus for SCADA
connectivity.
SDI-12
Plug & Play interface to Hydrolab DS5 and MS5 sondes to provide measurement
data in setpoint sampling applications.
Note: Hydrolab plug and play capability
requires firmware v5.43 or greater to be installed in the sonde.
