Supported Applications

The Omega CDH-SD11 Series is a portable conductivity, TDS (Total Dissolved Solids), and salinity meter featuring real-time SD card data logging. Designed for professional use with a large LCD display, the series supports long-term monitoring via a tripod receptacle mountable design.

Operating Conditions & Performance

The CDH-SD11 operates within a temperature range of 0~90°C with a temperature accuracy of ±0.5 °C. Measurement capabilities include:

Conductivity (K=1 Supplied): 30 uS/cm to 20 ms/cm, resolution 0~1999 uS/cm.
Conductivity (K=10 Option): 500 uS/cm to 199 mS/cm.
TDS: Ranges of 0 to 19.99 ppm, 0 to 199.9 ppm, 0 to 1999 ppm, 0 to 19.99 ppt, and 0 to 199.9 ppt.
Salinity: 0~42.0 ppt (Sea water).

Accuracy for Conductivity, TDS, and Salinity is specified as ±1% of full scale + 1 digit. The device includes built-in temperature compensation selectable between Thermistor 30K and 10K ohm.

Configuration Options

Sensor & Electrode Options

The series utilizes a BNC connector for the probe interface. Two electrode configurations are documented:

CDE-11G K=1 (Graphite type) supplied.
CDE-11P K=10 (Platinum type) available as an option.

The sensor body is constructed of ABS, with a graphite plate wetted material. The probe dimensions are 12x120mm overall length with a cable length of 1 M and a 3.5 mm diameter phone jack for the ATC temperature sensor.

Data Logging & Power

The meter supports SD memory cards up to 8GB capacity (SD card capacity: 1GB to 8GB). Sampling time is configurable from Auto 0, 2 secs, 5 secs, 10 secs, 15 secs, 30 secs, 60 secs, 120 secs, 300secs, 600 secs, 900 secs, to 1800 secs and 1Hr. A manual press of the ADJ button saves data once when sampling time is set to 0 second.

Power is supplied by AAA batteries x 3 pcs or an optional 9V AC/DC adaptor. The meter dimensions are 175mm x 58mm x 32mm (With BNC connector).
