The HM Digital DM-2 is a commercial monitor designed to measure TDS (Dissolved Solids) levels in feed and filtration system-treated water. It has an automatic shutdown feature to save battery power.
With its shielded cables and diagnostic messages, this rugged instrument is ideal for reverse osmosis (RO) and deionized water (DI) systems in drinking or potable water, water treatment, aquariums, hydroponics, and more.
FEATURES:
- Microprocessor technology provides high efficiency and accuracy.
- Display the TDS level of feed and purified water using electrode probes.
- Auto power off function saves battery power (auto power off after 3 minutes).
- Factory Calibrated: Our meters are calibrated using a 342 ppm NaCl solution. DM-2 has digital calibration.
- Diagnostic error messages.
- Shielded cables for sensors.
- Comes with two 1/4" diameter fittings (3/8" or 1/2" diameter fittings are also available).
Characteristics:
- Range: 0-9990 ppm Dual Range - Measures from 0 to 999 ppm with one ppm resolution. From 1000 to 9990 ppm, the resolution increases by ten ppm, indicated by a flashing "x10" icon.
- Accuracy: ±2%
- Conversion factor: NaCl (average value 0.5)
- Cable length: 46 inches (including sensor), shielded cables
- Sensor: Dual, 1/4" diameter for quick connection (model SP-3, included)
- Digital Calibration: Digitally calibrated at the factory for 342 ppm NaCl solution. Recalibration can be done on a per-line basis.
- Power supply: 2 AA batteries (included)
- Battery life: approximately two years
- Size: 11.6 x 6.8 x 1.8 cm
- Weight: 201.3 g
DM-2 vs DM-1:
- Designed for commercial and industrial applications.
- More durable housing, resistant to water.
- Digital calibration can be performed separately for each line.
- Improved design, including a large and clear LCD.
- Long waterproof shielded cables.
- Adjustable mount.
