Supported Applications

The Omega CDS107 is a portable, microprocessor-based multi-purpose meter designed for benchtop or handheld use to measure pH, ORP (Oxidation-Reduction Potential), conductivity, Total Dissolved Solids (TDS), salt, and temperature. The series supports water solutions in institutes, industrial labs, and production fields.

Operating Conditions & Performance

The CDS107 provides simultaneous measurement of the primary parameter and temperature on a large LCD display. Measurement ranges span from -2.00 to 16.00 pH; ORP ranges include -1999 to -200 mV, -199.9 to 499.9 mV, and 500 to 2000 mV; temperature covers 0 to 110°C; conductivity spans four ranges from 0.0 to 199.9 µS up to 20.0 to 100.0 mS; TDS ranges extend from 0.0 to 131.9 ppm through 13.2 to 66.7 ppt; and salt measurements cover 0.0 to 99.9 ppm through 10.0 to 50.0 ppt.

Accuracy specifications are ±0.01 + 1 digit for pH, ±2 + 1 digit for ORP, and ±0.2 + 1 digit for temperature. Conductivity, TDS, and Salt measurements carry an accuracy of ±2% FS. Resolution is provided at 0.01 pH; 0.1/1 mV for ORP; 0.1°C for temperature; variable steps (0.1/1 µS or 0.01/0.1 mS) for conductivity; and corresponding ppm/ppt resolutions for TDS and Salt.

Automatic Temperature Compensation (ATC) is available for pH measurements from 0 to 100°C, and for Conductivity, TDS, and Salt parameters from 0 to 50°C. The unit features a splash-proof housing with a rubber protective holster and includes an auto shut-off function after 10 minutes of non-use.

Configuration Options

The CDS107 series is configured as a complete system for field or lab analysis, powered by a 9V battery or AC adaptor. The meter supports data storage for up to 150 points and includes minimum/maximum functions.

  • Power Supply: 9V battery or AC adaptor (CDS100-PS replacement available).
  • Housing & Dimensions: Splash-proof housing with rubber protective holster; overall dimensions are 76 W x 114 L x 32 mm D (3 x 4.5 x 1.25"); weight is 260 g (9.17 oz).
  • Sensor Options: Includes pH electrode, conductivity cell, and temperature probe; ORP electrode available as an optional accessory.
  • Calibration & Accessories: Supports simple 5-point calibration with percentage slope indication. Standard kit includes Buffer 7.00 (50ml), Buffer 4.01 (50ml), 1413µS solution (50ml), carrying case, neck strap, and operator's manual.
  • Approvals: CE marked; backed by a 1 YEAR WARRANTY.

Key Product Differences

The primary model CDS107 is described as a benchtop/handheld meter for pH, ORP, conductivity, TDS, salt, and temperature. Replacement parts include the CDSB100-CDE replacement conductivity cell and various calibration solutions (pH buffers 4.01/7.00/10.01; Conductivity standards at 10 µmho/cm, 1413 µmho/cm, 1500 µmho/cm, and 45000 µmho/cm). ORP probes are sold separately.

Is this meter nitric acid compatible? What are the wetted materials used?

Asked by: Nitricity1
Thank you for your inquiry about the meter. The wetted material is an epoxy which is not chemically compatible with Nitric acid. A suggested pH probe is the PHE-5580 series which is a stainless steel body that is good up to 50% concentration.

What is the different between Salt mode and TDS mode?

Asked by: dd123
Thank you for your inquiry about the portable meter. Salt mode is measuring the percentage of salinity in samples and TDS is Total Dissolved Solids and represents the total concentration of dissolved substances in water. TDS is made up of inorganic salts, as well as a small amount of organic matter.
