The VG-METER-200 is a low cost hand held soil moisture meter with a professional digital display. This meter can measures and stores soil moisture, ambient temperature and light.
This meter uses the VH400 soil moisture sensor, and presents soil moisture results as a simple percentage (VWC). Light is also returned as a simple to understand percentage, where 0% is dark, and 100% is full sunlight. The VH400 sensor is included and integrated into the meter.
The ambient temperature displayed can be either be in Celsius or Fahrenheit. The temperature sensor can be calibrated for even greater accuracy.
Probes come standard with a 1 meter cable. The probe is waterproof, and about 5 inches long. Because it is slender it can be used to measure soil moisture in potted plants, as well as the ground. Because it uses a capacitive based VH400 probe, it never corrodes, is insensitive to soil salinity, and gives very precise readings.
The meter comes in two varieties, one with a USB interface and one without. The version with the USB interface, can stream data to a computer through most communication programs such as Windows Hyperterminal. The USB version comes with a mini-USB cable.
