    Discrepancy to flag. Bosch states an infrared accuracy of ±3.0°C on its own datasheet, while several French retailers list ±2°C for this same model. Value used here: the manufacturer's.

    Observations

    • Second discrepancy. Several retailers describe the GTC 400 C with a -20 to 600°C range and a 256 × 192 sensor, which are actually the GTC 600 C's specs. The two models are routinely mixed up in retailer listings.
    • Bosch publishes NO frame rate at all for this model.
    • Very wide 53° field of view for only 160 pixels. The recalculated spatial resolution is the lowest in the entire comparison.
    • Bosch publishes NEITHER the spectral band, NOR the pixel pitch, NOR the radiometric format: only .jpg is mentioned as a file format. Re-analyzing temperatures after the fact is therefore not documented as possible.
    • 3-year warranty conditional on registering the product within 4 weeks of purchase; otherwise, 1 year.
    • Dual power supply. Bosch 12V battery or four AA batteries, which is unique in this comparison.
