SmartReader Plus 10 - Three-Channel RTD Temperature Logger
The SRP-10 is a high-accuracy RTD data logger designed for demanding applications from cryogenic storage to high-heat processes. It accepts 2-, 3-, and 4-wire RTDs (best accuracy with 4-wire) and combines three external channels with an internal ambient channel for wide-ranging monitoring.

Key Features

  • Four channels – 3 external RTD channels + 1 internal thermistor for ambient temperature
  • Supports 2-, 3-, and 4-wire RTDs (highest accuracy with 4-wire)
  • Wide measurement range: -230°C to +300°C (-382°F to +572°F)
  • High accuracy: ±0.3°C (±0.54°F) + resolution or ±0.06% full scale
  • Memory capacity: 128 KB (up to 87,000 readings)
  • User-selectable sampling: from 25 per second to once every 8 hours
  • Battery powered with long-life 3.6V lithium cell (external power options available)
  • Networking: link up to 10 SmartReader Plus loggers together

Description Specifications Accessories Software Documentation Q&A Calibration

The SmartReader Plus 10 (SRP-10) is a proven RTD data logger built for research, QA, and temperature-critical industrial applications. With four total channels — three external RTD inputs and one internal thermistor channel — the SRP-10 delivers the accuracy, flexibility, and ruggedness required in industries where reliable temperature monitoring is non-negotiable.

Supported RTD Types

  • 2-wire RTDs: Supported, though lead resistance may introduce error.

  • 3-wire RTDs: Common in industrial use; compensates for lead resistance in balanced wiring.

  • 4-wire RTDs: Recommended for highest accuracy; eliminates lead resistance effects.

Any platinum RTD probe with a Temperature Coefficient of Resistance (TCR) of 0.00385 can be used with the SRP-10.

Calibration

Data loggers are often used in highly regulated environments such as food and pharmaceutical production and storage where strict safety regulations apply. Regulatory agencies generally require proof of calibration.

ACR calibrations are performed using reference standards that have been calibrated and are traceable to the US National Institute of Standards & Technology (NIST). This ensures that all ACR data loggers meet, and perform to, their published specifications, allowing you to be confident that they will assist you in achieving your compliance requirements.

Calibration certificates are provided with every calibration we perform. ACR Systems is an ISO 9001:2015 registered company and calibration records are kept as part of our quality system and can be made available for customer audits.
