Infrared Temperature Sensor for TDR 350 Only – Fast, Accurate, and Reliable Surface Measurement | Spectrum Technologies

The Infrared Temperature Sensor for TDR 350 enables non-contact surface temperature measurement for turf and soil analysis. Designed for direct integration with the TDR 350 soil moisture meter from Spectrum Technologies, it delivers precise and repeatable measurements. With a 10° field of view and a 6:1 optical ratio, it captures temperature data over a 15 cm area located 8 cm in front of the probe block.

Key Benefits:

• Quick installation: easily mounts to the TDR 350 using the included bracket and screw set.
• Instant readout: temperature values display in real time on the TDR screen.
• High accuracy: ±0.5 °C between 0 °C and 50 °C with 0.1 °C resolution.
• Non-invasive sensing: measures temperature without touching the surface.
• Robust construction: reinforced cable and durable sensor for field applications.

Main Specifications:

• Measurement range: –40 °C to +100 °C (–40 °F to +212 °F).
• Resolution: 0.1 °C (0.1 °F).
• Accuracy: ±0.5 °C (0–50 °C).
• Optical ratio: 6:1.
• Field of view: 10° cone, 15 cm diameter at 8 cm distance.
• Cable length: 17 cm (6.8 in).
• Sensor length: 3 cm (1.2 in).
• Operating temperature: 0 °C to 50 °C.

Typical Applications:

• Monitoring turf and soil surface temperatures for irrigation and thermal stress management.
• Use on sports fields, golf courses, greenhouses, and agricultural plots.
• Analysis of temperature, moisture, and EC correlations in agronomic studies.

Why Choose This Sensor:

• Instant, accurate, and repeatable surface temperature measurements.
• Full compatibility with the TDR 350 moisture meter.
• Plug-and-play installation—no modification required to the main probe.
• Ideal for professionals in turf management, agronomy, and research applications.
