Monitor temperature, humidity and dew point with confidence using the C.A 1246 Thermohygrometer & Data Logger.

When environmental conditions matter, a single temperature reading is rarely enough. A temperature data logger gives you a recorded history of changing conditions, helping you identify fluctuations, review trends and maintain reliable measurement records.

The C.A 1246 Thermohygrometer – Part No. P01654246, available from Apex Test Instruments in Singapore, combines temperature, relative humidity and dew-point measurement with programmable data recording in one portable instrument.

With storage for up to 1 million measurements, USB and Bluetooth connectivity, configurable alarms and field-ready construction, it is designed for professionals who need more than a basic thermometer.

Key Capabilities:

• Temperature measurement from -10°C to +60°C
• Relative humidity measurement from 3% to 98% RH
• Dew-point measurement
• Record up to 1 million measurement points
• USB and Bluetooth communication
• Programmable recording
• Configurable alarm thresholds
• Min, Max and Hold functions
• Backlit display for easier field use
• IP54-rated enclosure
• °C and °F measurement display

Temperature-sensitive environments do not remain constant. Room conditions can change after operating hours. Humidity can rise unexpectedly. HVAC performance can fluctuate. Storage areas can develop hot or humid zones that may not be obvious during a manual inspection.

A conventional thermometer tells you the condition at the moment you check it. A data logger provides something more useful: a record of what happened over time.

The C.A 1246 can perform spot measurements or record readings according to a programmed schedule, giving maintenance teams, engineers, laboratory personnel and facility professionals data they can review rather than relying solely on occasional manual checks.

This makes it useful for applications such as:

• Industrial and manufacturing environments
• Laboratories and testing facilities
• Warehouses and storage areas
• HVAC investigations
• Building and facility inspections
• Environmental condition monitoring
• Temperature and humidity surveys
• Quality-control activities
• Process and workplace monitoring

When temperature and humidity influence equipment, materials, processes or working conditions, having a recorded measurement history can help teams identify when conditions changed and investigate the possible cause.

Measure Three Environmental Parameters with One Instrument

The C.A 1246 combines:

Ambient Temperature

Measure temperatures across a range of -10°C to +60°C.

Relative Humidity

Monitor humidity between 3% and 98% RH.

Dew Point

Assess dew-point conditions to better understand moisture and condensation risk.

Instead of carrying separate instruments for routine environmental checks, technicians can obtain these measurements from one portable device.

Record Up to 1 Million Measurements

Continuous monitoring can generate large volumes of data. The C.A 1246 can store up to 1 million measurement points, making it suitable for extended monitoring and detailed environmental investigations.

Recording can be started manually or programmed according to the monitoring requirement.

Set Thresholds and Identify Abnormal Conditions

Through Data Logger Transfer software, users can configure alarm thresholds and recording triggers.

If a monitored parameter moves beyond the selected threshold, the instrument can provide a visual alert. Recording can also be triggered based on an alarm threshold.

This helps teams focus on abnormal environmental conditions instead of manually checking every individual reading.

Transfer and Review Data via USB or Bluetooth

Recorded information is useful only when it can be accessed easily.

The C.A 1246 supports both:

• USB connectivity
• Bluetooth communication

Measurement data can be transferred for further review and reporting using compatible software.

Designed for Practical Field Measurement

The instrument includes everyday functions technicians need during inspections:

• Min reading
• Max reading
• Hold
• Alarm functions
• Backlighting
• °C / °F selection

Its IP54 enclosure provides added protection for field use, while compatibility with the Multifix accessory gives users additional mounting options.

For environmental monitoring, measurement quality matters. The C.A 1246 is manufactured by Chauvin Arnoux and identified by manufacturer reference P01654246.

Technical Highlights:

• Temperature Range: -10.0°C to +60.0°C
• Temperature Accuracy: From 10°C to 40°C: ±0.5°C ± 1 count
• Relative Humidity Range: 3.0% to 98.0% RH
• Relative Humidity Accuracy: From 10% to 90% RH: ±2% RH ± 1 count
• Dew Point: Measures dew-point temperature in addition to ambient temperature and relative humidity
• Data Storage: Up to 1 million measurement points
• Communication: USB and Bluetooth
• Protection Rating: IP54
• Dimensions: 187 × 72 × 32 mm
• Weight: Approximately 260 g with batteries

These capabilities make the C.A 1246 suitable for both quick field measurements and longer-term environmental data recording.

Choosing measurement equipment is not simply about finding a device with the right specification. It is also important to identify the right instrument for the intended application.

Apex Test Instruments supplies professional test and measurement equipment in Singapore, including instruments for electrical, industrial and environmental measurement requirements.

What is a temperature data logger?
A temperature data logger is an electronic measuring instrument that records temperature readings automatically over time. Unlike a standard thermometer that provides a reading at one moment, a data logger creates a measurement history that can be reviewed for trends and temperature changes.

What is a temperature data logger used for?
Temperature data loggers are commonly used to monitor environmental conditions in warehouses, laboratories, manufacturing facilities, storage areas, HVAC systems and other temperature-sensitive environments. They help users track how conditions change over a defined monitoring period.

Does the C.A 1246 measure humidity as well as temperature?
Yes. The C.A 1246 is a 3-in-1 thermohygrometer that measures ambient temperature, relative humidity and dew point. It measures temperature from -10°C to +60°C and relative humidity from 3% to 98% RH.

Can temperature data from the C.A 1246 be transferred to a computer?
Yes. The C.A 1246 supports USB and Bluetooth communication. Using compatible Data Logger Transfer software, users can access recorded measurements, configure recording parameters and set alarm thresholds.

Whether you need to investigate changing room conditions, record environmental measurements or monitor temperature and humidity over time, the right instrument gives you data you can actually use.

The C.A 1246 Thermohygrometer & Data Logger combines temperature, humidity and dew-point measurement with high-capacity recording, configurable alarms and convenient data transfer in one portable unit.
