Performance, Upgraded.
Portable soil moisture meter allows you to obtain readings on the go at the press of a button. Variable rod length options provide soil moisture measurements at your ideal root zone. With new enhancements, the TDR 150 provides significant improvements in performance and measurement accuracy for optimal turf and soil environments.

Color-coded to represent a scale of turf firmness, moisture, surface temperature and EC
Free download from App store or Google Play
Works on iOS and Android devices
CALIBRATION FEATURE - If you purchased your meter before 2012, the TDR family of soil moisture meters now includes the option to perform a calibration on an individual meter. The calibration is done in 2 media; air and distilled water. This new feature took effect with firmware version 6.5 and is included with units shipped after January 1, 2012 (purchased directly thru Spectrum). Meters with firmware versions earlier than v. 6.5 can be upgraded by purchasing and installing an updated microcontroller chip (Item #CHIP-TDR3, see above table for purchasing). Firmware version 6.5 or higher required for FieldScout Bluetooth Device connection.
Measurement Principle: Time - domain measurement methods
Measurement Units: Percent Volumetric Water Content (VWC)
Resolution: 0.1% VWC
Accuracy: +- 3.0% VWC with Electrical Conductivity (EC) < 2 mS/cm
Range: 0% to saturation (Saturation up to about 50% volumetric water depending on soil type)
Battery/Life: 4 AA lithium batteries; approximately 100,000 readings without backlight
Data Logger: 50,000 measurements
EC Range: 0 to 5 mS/cm, Resolution: 0.01 mS/cm, Accuracy: +/- 0.1 mS/cm
Temperature Range: -30°C to 60°C, Resolution: 0.1°, Accuracy: +/- 1°C
