Temperature monitoring has been a task relegated to simple and unexciting chart recorders. Think temperature recording and you think clumsy boxes that require constant attention with paper and pen refills. This is no longer true with the MMS3000-T4. The MMS3000-T4 is the low-cost temperature-dedicated product in the revolutionary MMS3000 series. With the MMS3000-T4 you can take extended recordings of up to 9,999 readings, and up to 60 hours between samples. The result is a test that can last weeks without the need to touch anything. Once finished, simply connect the unit to a standard PC and within minutes your data is easily downloaded for further analysis using MAS™, our Windows based data manipulation software. Do you need to review temperature data in the field or on the plant floor away from a PC? Then the MMS3000-T4 is the instrument of choice. The large LCD enables you to graphically review recorded data simply by pressing a few keys. Windows based software for flexible data manipulation. Producing a variety of graphs and printout options. ITEM SPEC REMARKS Model: MMS3000-T4 Incorporating 4 Temperature Channels   TEMPERATURE RANGE T Type Thermocouple -418 to +743°F (-250 to +395°C) Operating temperature range E Type Thermocouple -418 to +1823°F (-250 to +995°C) is determined by operating J Type Thermocouple -346 to +2183°F (-210 to +1195°C) range of thermocouple K Type Thermocouple -418 to +2498°F (-250 to +1370°C)   TEMPERATURE RESOLUTION Above -148°F (-100°C): 0.1°F or °C At or below -148°F (-100°C): 1°F or °C Effective resolution decreases at or below -148°F (-100°C)   TEMPERATURE ACCURACY Above -148°F (-100°C): ±0.1% of reading ±0.9°F (0.5°C) At or below -148°F (-100°C): ±1% of reading ±0.9°F (0.5°C) Total measurement accuracy depends on MMS3000-T4 and thermocouple accuracy. Only MMS3000-T4 accuracy is given here. MMS3000-T4 temperature 73 ± 9°F (23 ± 5°C), charger off.
