Description
Overview
The Fluke Calibration Chub-E4 is a precision multi-channel thermometer designed for laboratory, calibration, and field temperature measurement. With four configurable input channels supporting PRTs, RTDs, thermistors, and thermocouples, it provides accurate temperature measurements across diverse applications. The instrument features automatic date and time stamping, configurable data logging with up to 8,000 readings, and flexible display options for different measurement units and formats.
The Chub-E4 achieves high accuracy with ±0.004°C for PRTs at -100°C and ±0.0025°C for thermistors at 25°C. Its battery-powered design enables 8 hours of continuous operation and portable field measurements. The unit supports RS-232 and optional IEEE-488 communication for integration with automated calibration systems and data management.
