Delta Ohm HD2127.2 Portable Logger Thermometer with 2×Pt100 Inputs

The Delta Ohm HD2127.2 is a professional two‑channel thermometer and data logger designed for precise temperature monitoring in the laboratory and in the field. It offers dual Pt100 inputs with simultaneous readings and A–B differential display, a wide measuring range from −200 °C to +650 °C and instrument‑class accuracy of ±0.01 °C excluding probe error. With robust IP66 protection, long battery life and real‑time PC connectivity, it delivers reliable measurements shift after shift. Available at Stratosens.com, it arrives ready to work with case, batteries, USB cable and software, while the versatile TP47 probe family lets you tailor the system to immersion, penetration, surface or air measurements.

Key Benefits and Applications

• Two channels for faster work — Measure on two points at once and view the A–B temperature difference to profile systems, check gradients and balance processes in HVAC, industrial maintenance and energy audits.
• High accuracy for demanding tasks — Instrument accuracy of ±0.01 °C supports calibration tasks, quality control, laboratory research and any application where small thermal drifts matter.
• Wide range from cryogenic to hot processes — From −200 °C to +650 °C with Pt100 probes to cover freezers, environmental chambers, food processing and high‑temperature equipment verification.
• Rugged and weather‑resistant — IP66 housing with ABS and rubber protection stands up to field inspections, on‑site commissioning and repetitive daily use.
• Efficient data logging — Store up to 32,000 pairs of readings with selectable intervals from 1 s to 1 h, then export with DeltaLog9 for audit trails, reports and compliance.
• Smart probe ecosystem — SICRAM probes auto‑recognise with stored calibration data, reducing setup time and ensuring traceable measurements in GMP, ISO 9001 and HACCP contexts.
• Ready for real‑time monitoring — USB and RS232 enable live trending on a PC or portable printing for fast documentation on production floors and service visits.
• Portable productivity — Long battery autonomy, a large dual display and an ergonomic layout make it ideal for technicians and researchers on the move.
