Product Introduction

This compact mapping platform combines a rugged measurement mainframe, a local touch interface and removable thermocouple input modules in one transportable enclosure. Multiple sensors are sampled against a common clock so engineers can compare temperature distribution across a chamber or load throughout the same study. Internal storage preserves the run locally, while network and USB interfaces support study transfer and analysis without tying the instrument to a general-purpose computer during collection.

Key Features

Synchronized multi-channel acquisition reveals spatial hot and cold zones.

Removable input modules simplify sensor replacement and configuration changes.

Local touch controls support stand-alone study setup and live review.

Cold-junction compensation stabilizes thermocouple measurements at the input bank.

Internal memory safeguards complete mapping records if the network is unavailable.

Battery-backed operation helps a study continue through brief supply interruptions.

Customer Product Concerns

Thermal equipment can meet a controller setpoint while still containing local hot or cold zones, so qualification requires simultaneous measurements distributed throughout the usable volume or process load.

Independent spot readings cannot show how the whole chamber behaves at the same moment.Common-clock channel scanning produces time-aligned measurements from every mapped location.

A sensor fault can invalidate a long qualification run.Live channel status and removable input modules help identify an open or unstable sensor before the study proceeds.

Network loss may interrupt data collection in remote equipment areas.Stand-alone controls and internal memory keep the acquisition task local to the instrument.

Different assets require different channel counts and sensor types.Modular inputs and selectable thermocouple configurations adapt the platform to each mapping plan.

Typical Applications
