Record Temperature Trends with ±0.1 % Accuracy
The 3441 and 3442 provide high-resolution measurements across a wide range of temperatures using K type thermocouples. With its drip-proof design, the 3442 delivers extended versatility, allowing use in moisture-prone environments when used with a special-purpose temperature probe.
• Model 3441 (°C only)
• Model 3441-02 (°C/°F selectable)
• Model 3442 (°C only, waterproof construction)
These products cannot perform measurement alone. Please purchase a temperature probe separately.
Model 3442: IP54 waterproof construction
• -100 to 199.9 ˚C: 0.1 ˚C resolution, 200 ˚C to 1300 ˚C: 1 ˚C resolution
• More than 200 hours (1 week) of continuous operation on a single battery
• Max./Min. value recording function and sensor disconnection check function
■ Basic specifications (Accuracy guaranteed for 6 months)
