Multi-Channel Temperature Data Loggers

Multi-channel temperature data loggers record simultaneous temperature readings from multiple sensor inputs — storing time-stamped datasets for cold chain verification, pharmaceutical validation, industrial process monitoring, environmental compliance, and research instrumentation applications where tracking temperature at several points simultaneously is a regulatory or operational requirement.

Input compatibility covers the primary temperature sensor types used in industrial and laboratory applications. Thermocouple inputs accept K, J, T, E, N, R, S, and B types — covering ranges from -200°C on cryogenic T-type applications to +1,820°C on R and B-type inputs for furnace and kiln monitoring. RTD inputs support PT100 and PT1000 sensors delivering measurement accuracy of ±0.1°C for pharmaceutical and food safety applications requiring tighter tolerances than thermocouples provide. Furthermore, NTC thermistor inputs on compact data loggers cover -40°C to +125°C at high resolution — suited for cold room, refrigerator, and freezer temperature mapping during pharmaceutical validation surveys.

Channel counts range from 4 on portable handheld loggers to 128 and above on modular rack systems. Logging intervals program from 1 second for dynamic process monitoring to 60-minute averages for long-term environmental surveys. Alarm outputs trigger relay contacts, visual indicators, and wireless notifications when any channel exceeds configured threshold values. Additionally, the Yokogawa GP10 paperless recorder displays real-time temperature trend graphs across all channels on a colour touchscreen while simultaneously logging to compact flash storage — meeting 21 CFR Part 11 electronic record requirements for pharmaceutical GMP environments.

Wireless models transmit data via Wi-Fi, Bluetooth Low Energy, or cellular networks — enabling remote temperature monitoring of geographically distributed cold chain points, warehouse storage areas, and field measurement positions without data cable infrastructure. USB and Ethernet connections support direct PC data download and network integration with building management and SCADA systems through Modbus TCP protocols.

These loggers serve Pakistan’s pharmaceutical manufacturing and cold storage operations in Karachi and Lahore, food processing and cold chain logistics operators, PCSIR and university laboratory temperature monitoring programs, hospital blood bank and vaccine storage facilities, and oil and gas processing plant instrumentation teams in Sindh and Balochistan requiring reliable multi-point temperature recording for compliance and process control.

Tactical Supply Pakistan supplies multi-channel temperature data loggers for pharmaceutical validation, cold chain monitoring, industrial process recording, and laboratory instrumentation procurement across Pakistan.
