DescriptionThe MH 3750 is a portable digital thermometer designed for use with Pt100 sensors (4-wire). Precision measurements and reliable signal processing are achieved through powerful sensors and electronic linearization of the characteristic curve. The ergonomic housing and sealed membrane keypad make the instrument suitable for both field and laboratory use.
Main functions- Measurement ranges: -199.99 to 199.99°C or 200.0 to 850.0°C
- Resolution: 0.01°C (low range) or 0.1°C (high range)
- Accuracy: ±0.015% of range ± 1 digit
- Input: 1 x mini-DIN connector for Pt100 (4-wire)
- Automatic sensor recognition via DIN connector (plug-and-play)
- Display and alarm functions (visual and acoustic)
- Statistical functions (MIN / MAX, etc.)
- Expandable analog output
Datalogger and data transferBuilt-in recording functions: STORE mode (manual recording, capacity 99 points) and CYCLE mode (automatic recording, capacity up to 16,200 points). Stored measurements include date and time using a real-time clock. Data transfer to a PC is performed via a serial interface; compatible software (e.g. EBS 20 M, SOFT 3050) enables extended display, processing and export to standard formats for analysis (e.g. spreadsheets).
Use and designDesigned for a variety of industrial and laboratory applications with many compatible Pt100 probes. Portable housing with dust- and moisture-resistant membrane keypad for reliable operation in the field. User-defined characteristic curve: up to 50 value pairs.
CalibrationTraceable to international standards; optional COFRAC calibration available (certificate and number of calibration points to be specified at order).
