Waterproof Professional Series Combo Meter, 7, White/Purple

The OM-100 is a versatile combo meter that offers a range of features for measuring various water quality parameters. This compact and waterproof device is designed to provide accurate and reliable measurements for electrical conductivity (EC), total dissolved solids (TDS), and temperature.

Starting with the electrical conductivity range, the OM-100 can measure from 0 to 9990 μS and 0 to 9.99 mS. The TDS range covers 0 to 8560 ppm (mg/L) and 0 to 8.56 ppt. The temperature range spans from 0 to 80 degrees Celsius (32 to 176 degrees Fahrenheit).

The instrument's resolution is impressive, with 0.1 μS/ppm/mS/ppt for readings from 0 to 99, 1 μS/ppm for 100 to 999, and 10 μS/ppm for 1000 to 9990. The temperature resolution is 0.1 degrees Celsius, and the accuracy is within ±2% of the reading.

The OM-100 features a non-linear conversion factor for EC to TDS, allowing users to select between KCl, 442TM, or NaCl solutions, depending on their needs. This versatility ensures that the device can provide accurate TDS measurements in a variety of water conditions.

Calibration of the OM-100 is a straightforward process, with a digital calibration system activated by a simple push-button. The detachable platinum electrodes in the probe ensure reliable and consistent measurements.

In terms of power, the OM-100 is powered by three 1.5V button cell batteries (model 357A), which are included with the device. This compact design is complemented by the IP67 waterproof housing, making the meter suitable for use in various environments, from laboratories to outdoor field work.

When it comes to the physical dimensions, the OM-100 measures 7.3 inches in height, 1.3 inches in width, and 1.3 inches in depth (18.5 x 3.4 x 3.4 cm). The overall weight of the device is 0.20 pounds (3.2 oz), making it a lightweight and portable option.

The OM-100 is a product of collaboration between the design teams in the USA and Korea, ensuring a blend of innovative features and quality craftsmanship. With its comprehensive measurement capabilities, user-friendly calibration, and durable waterproof construction, the OM-100 is an excellent choice for a wide range of water quality monitoring applications.
