High Precision Portable Thermometer — Dostmann P795

Achieve lab‑grade temperature control wherever you work with the Dostmann P795, a portable reference thermometer engineered for uncompromising accuracy and stability. This dual‑channel Pt100 instrument delivers ±0.015 °C accuracy in the critical range and a razor‑fine 0.001 °C resolution, supported by onboard memory for 6,000 measurements and a USB interface for effortless documentation. Smart probe technology with automatic coefficient transfer streamlines setup, so you can focus on results. Available from Stratosens.com, the P795 is the reliable choice for calibration baths, climatic chambers, ovens and temperature‑critical processes.

Key Benefits and Applications

• Reference‑grade accuracy for validation — Verify and optimise processes with confidence thanks to high precision in the most used temperature span, ideal for QA, method validation and standardisation.
• Dual‑channel efficiency — Measure two points simultaneously or view T1‑T2 differential to accelerate comparative testing, gradient checks and side‑by‑side probe verification.
• Smart probe workflow — Use Pt100 Smart probes with integrated memory so calibration coefficients transfer automatically to the instrument, reducing setup time and avoiding manual entry errors.
• Portable and robust design — A compact ABS housing, clear two‑line LCD and approximately 20 hours of battery life support dependable field and laboratory work without interruption.
• Traceable quality assurance — Pair with a calibration certificate for full traceability, supporting ISO‑driven audits and regulated environments in pharma, food, energy and research.
• Seamless data handling — Store 6,000 readings and select logging intervals from 1 second to 30 minutes, then offload data via USB for analysis and reporting.

Featured technical specifications

• Measurement inputs — Two inputs for Pt100 sensors according to EN 60751 with 8‑pole DIN 45326 connectors for secure, low‑noise measurements.
• Measuring range — From −200 °C to +850 °C when used with suitable Pt100 probes, covering cryogenic to high‑temperature applications.
• Accuracy — ±0.015 °C from −50 °C to +199.99 °C, outside this span typically 0.025% of reading for consistent performance across the full range.
• Resolution — 0.001 °C from −200 °C to +200 °C, 0.01 °C in the remaining range for precise trend recognition.
• Differential measurement — Display T1, T2 and T1‑T2 to characterise gradients, heat flows and comparative sensor behaviour.
• Data logging — Internal memory for 6,000 measurements with user‑selectable intervals from 1 s to 30 min to match your process dynamics.
• Interface — USB output for easy data transfer and integration into digital records and SOP workflows.
• Display and functions — Two‑line LCD with HOLD, MIN, MAX and AVG to capture and review key values directly at the instrument.
• Power — 9 V battery supply with approximately 20 h of operation, optional mains adaptor for continuous use.
• Operating conditions — Works from 0 °C to +40 °C for typical laboratory and on‑site environments.
• Dimensions and weight — 200 × 85 × 40 mm and 300 g for an ergonomic, portable form factor.
• Probe ecosystem — Compatible with a wide range of Pt100 probes including Smart probes with EEPROM storing R0ABC coefficients and multipoint adjustments for fast, accurate deployment.
• Construction — Durable ABS housing designed for daily professional use and reliable handling.
