In any process-driven industry, temperature and humidity are not just numbers on a display — they are records of quality, compliance, and safety. A pharmaceutical cold room that drifted 2°C overnight, a furnace that spiked during a shift change, a food storage unit with rising humidity — none of these events matter unless they are recorded. Data loggers exist for exactly this reason: to capture what instruments see, store it reliably, and make it available for analysis without any human intervention.
At Countronics, we have been manufacturing temperature and humidity data loggers from our facility in Sahibabad, Ghaziabad since 1978. Our USB pen drive data loggers — the CT716, CT708, and CT700 — are designed for industrial use: robust, accurate, easy to operate, and requiring no proprietary software to retrieve or read the stored data.
Why Industries Cannot Afford Manual Temperature Recording
Manual temperature logging — where an operator reads a thermometer and writes it in a register every hour — has three fundamental problems. First, it creates gaps: nobody records at 3 AM. Second, it introduces human error in both reading and transcription. Third, it produces data that is difficult to audit, graph, or trend over time. Automated data loggers solve all three problems simultaneously. They record at set intervals around the clock, store timestamped values in memory, and output the data in a format that opens directly in Microsoft Excel — giving engineers and quality managers an immediate, reliable record without any additional software or processing.
CT716 — 16 Channel Temperature Scanner Logger with LCD Display
The CT716 is our flagship multichannel logger, capable of monitoring up to 16 temperature points simultaneously. It accepts J-type, K-type, and R-type thermocouples as well as PT100 RTD sensors, making it compatible with virtually all standard industrial temperature sensors. The instrument features a four-line alphanumeric LCD display with backlight for clear reading even in dimly lit plant environments. Data is saved at user-selectable intervals directly to a USB pen drive inserted in the front panel, in CSV format compatible with Microsoft Excel. The number of active channels is user-selectable, and the instrument supports both Auto and Manual scanning modes. Cold junction compensation is automatic for thermocouples, and three-wire input is supported for PT100. The CT716 is widely used in multi-zone furnaces, ovens, autoclaves, pharmaceutical stability chambers, and food processing lines where simultaneous multi-point recording is essential. https://www.countronics.com/product/16-channel-data-logger-data-acquisition-systems-with-direct-usb-pen-drive/
CT708 — 8 Channel Universal Temperature Logger with LED Display
The CT708 provides the same USB pen drive data logging capability as the CT716 but in an 8-channel configuration with a bright LED display for high-visibility reading at a distance. In addition to thermocouple and PT100 inputs, the CT708 also accepts 4-20mA process inputs, with the Low, High, and resolution individually settable per channel. This makes it suitable for mixed-sensor applications where some channels carry temperature sensors while others carry 4-20mA transmitters for pressure, flow, humidity, or other process variables. The CT708 is the preferred choice for smaller process lines, laboratory environments, and applications where 8 measurement points are sufficient and LED display brightness is important. The logging rate is user-settable in minutes and seconds, and a digital offset is available for each channel for field calibration. https://www.countronics.com/product/8-channel-temperature-logger-for-usb-pen-drive/
CT700 — Humidity and Temperature Logger with USB Pen Drive
The CT700 is a dedicated humidity and temperature data logger that records both relative humidity (RH%) and temperature simultaneously on a USB pen drive. It uses a capacitive humidity sensor — with a dry/wet sensor option available on request — combined with a PT100 sensor for temperature. Separate displays show current humidity and temperature readings at all times. An internal real-time clock with battery backup timestamps every logged entry with date and time, making the CT700 ideal for applications requiring time-stamped environmental records. The logging interval is user-settable, and no separate software or drivers are needed — the CSV file on the pen drive opens directly in Excel. The CT700 is particularly well suited to pharmaceutical manufacturing areas, HVAC system monitoring, food storage facilities, cleanrooms, incubators, and any environment where maintaining and documenting RH and temperature within specified limits is a regulatory or quality requirement. https://www.countronics.com/product/humidity-temperature-logger-for-usb-pen-drive/
Common Applications Across Industries
Temperature and humidity data loggers from Countronics are used across a wide range of industries. In pharmaceuticals, they provide the validated environmental records required for GMP compliance in storage areas, cold rooms, and stability chambers. In the food industry, they document cold chain integrity from storage to dispatch. In industrial furnaces and heat treatment plants, they provide multi-zone temperature records that confirm process consistency and help troubleshoot quality issues. In HVAC and building management, they track environmental conditions over time for energy auditing and comfort management. In research laboratories, they provide continuous background monitoring of test environments without requiring manual attention.
No Software Required — Data Directly in Excel
A key design feature of all three models is that the stored data requires no proprietary software to access. The USB pen drive can be removed from the instrument at any time and inserted into any computer. The CSV file is immediately readable in Microsoft Excel, where engineers can plot trends, calculate averages, identify anomalies, and produce compliance reports without any additional tools or licences.
Conclusion
Reliable, continuous, and tamper-evident temperature and humidity records are no longer optional in most industries — they are the baseline expectation of quality systems, regulatory auditors, and customers alike. The CT716, CT708, and CT700 data loggers from Countronics deliver exactly this, with the simplicity of USB pen drive output and the accuracy of ISO 9001:2015 certified manufacturing.
