Supported Applications
The Omega HSM50 Digital Handheld Soil Moisture Meter is designed to check the moisture level of soil or other similar materials. The device measures moisture content using a 2-pin electrode probe that assesses the conductive ability of the sample and converts it into a percentage reading.
Operating Conditions & Performance
The HSM50 operates within an ambient temperature range of 0 to 50°C and requires operating humidity less than 80% R.H. It measures moisture content from 0 % to 50 % with a resolution of 0.1 %. Accuracy is specified as ± (5 % + 5 d) F.S. @ 23± 5°C, where F.S. denotes full scale. The sampling time is approximately 0.8 second.
Configuration Options
The series features a durable ABS-plastic housing and an LCD display measuring 28 mm x 19 mm. Key functional capabilities include:
• Data Hold: Freezes the display reading.
• Circuitry: Custom one-chip microprocessor LSI circuit.
The meter is powered by a DC 1.5 V battery (MN1500-4) with an approximate current draw of DC 12 mA. The included probe features a stem length of 8.7" (220 mm), a diameter of 0.4" (10 mm), and a total combined length (meter + probe) of 15.4" (392 mm). The meter body dimensions are 6.8" x 1.6" x 1.6" (172 x 40 x 40 mm).
Key Product Differences
The HSM50 is supplied as a complete unit including the instruction manual and battery, with a total weight of 267 g / 0.58 LB when the battery is included.
