When accuracy matters, a circular temperature chart recorder helps keep critical temperatures in check. This guide highlights models well-suited for refrigerators, freezers, and ambient environments, with clear data history for compliance and quality assurance. Readers who manage food service, medical storage, or lab environments can use these recommendations to choose the right device for constant monitoring, trend reporting, and easy visibility of changes over time.
| Product | Best For |
|---|---|
| Supco CR87B | Commercial refrigerators and freezers needing continuous data logging |
| Supco CR87J | Remote readings with Type J thermocouple for flexible placement |
| Dickson SL4350 | 7-day or 24-hour rotation with digital display for labs and kitchens |
| Supco CR87BC | Celsius monitoring with front-panel controls for quick setup |
| DeltaTrak 16100 (20 pack) | In-transit temperature tracking and easy pallet deployment |
Supco CR87B Temperature Monitor

The CR87B provides precision temperature monitoring for refrigerators, freezers, and ambient environments. It ships with a 6″ chart and a stainless steel tip probe for accurate readings. Best for commercial kitchens and storage facilities that require stable, traceable history over time. A potential limitation is the reliance on chart-printed history, which may require careful archiving for long-term audits.
Supco CR87J Fahrenheit Type J Chart Recorder

The CR87J uses a Type J thermocouple to deliver remote readings with a 6″ chart. It suits facilities needing flexible sensor placement and a broad measurement range. Choose this if you require remote data capture across multiple zones; avoid if you need non-remote logging in a single location with a simple interface.
Dickson SL4350 Temperature Chart Recorder

The SL4350 offers a digital display and flexible timing options (7-day or 24-hour rotation) with a Celsius/Fahrenheit switch. It’s well-suited for laboratories and kitchens needing easy-to-read data with adjustable rotation. Best for environments that require daily trend visibility; a limitation is that it may be less portable than compact units.
Supco CR87BC Celsius Chart Recorder

The CR87BC focuses on Celsius monitoring with a large LED display for easy temperature reading and front-panel controls for fast setup. Best for facilities that standardize on Celsius and need quick, on-site adjustments. A caveat is that it targets Celsius displays, which may require conversion tools for teams accustomed to Fahrenheit in some contexts.
Supco CR87B220C Celsius Recorder

This Celsius model extends the practical front-panel controls and a large LED display for straightforward Celsius readings. It’s ideal for users who need reliable Celsius monitoring across 6″ charts and quick setup. The product data suggests easy front-panel operation, making it suitable for busy environments; however, ensure the voltage matches your facility supply if selecting non-standard configurations.
DeltaTrak 16100 10-Day In-Transit Recorder

The DeltaTrak 16100 is designed for in-transit temperature monitoring, with a simple peel-and-stick pallet deployment and a readable Fahrenheit and Celsius chart. Best for supply chains requiring quick, in-transit visibility. A limitation is that it may be optimized for short-term shipping scenarios rather than long-term fixed-location use.
Buying Guide: Circular Temperature Chart Recorders
- Sensor type and placement: Remote sensing (Type J, thermocouples) offers flexible placement; direct-contact probes provide simple, single-location readings.
- Chart format and durability: 6″ charts are standard; consider stainless steel or rugged housings for harsh environments.
- Display and readability: LED displays help quick checks; large fonts reduce eye strain in busy kitchens and labs.
- Power requirements and voltage: Check voltage compatibility (110-120V vs. 220-240V) for your facility power supply.
- Data accessibility: Digital displays and log history support compliance; printed charts require archiving practices.
- Best-use scenarios: In-transit recorders suit shipments; fixed-location recorders suit cold storage facilities and kitchens.
- Ease of setup: Front-panel controls shorten setup time; remote sensors add flexibility but may require extra configuration.
Frequently Asked Questions
- What is a circular temperature chart recorder used for?
It continuously records temperature on a circular chart, often used in cold storage, food service, and transport to verify that temperatures remain within set ranges.
- Which model is best for in-transit monitoring?
DeltaTrak 16100 is designed for in-transit temperature tracking with pallet-friendly deployment and easy readouts.
- Do these devices require calibration?
Calibration needs vary by model and application; follow manufacturer guidelines for accuracy and compliance requirements.
- Should I choose Celsius or Fahrenheit displays?
Choose based on your team’s standard practice; many facilities run Celsius for global standardization, while Fahrenheit is common in the U.S.
- Are digital displays more reliable than chart-based readings?
Digital displays improve readability and real-time monitoring, but printed charts provide tangible history for audits and compliance.
- Can these recorders be used for both freezers and refrigerators?
Yes, most models are designed for use across refrigerators, freezers, and ambient environments, with appropriate temperature ranges.
