OM-HL-SP-Series

Supported Applications

The Omega OM-HL-SP Series is a single-channel, pen-size temperature and humidity USB data logger designed for refrigerator monitoring, cold-chain transportation, container transport, and data center applications. The device features an IP67 rating for waterproof and dustproof protection in these environments.

Operating Conditions & Performance

The series operates across a measurement range of -30~70°C and 0~100%RH, depending on the specific model variant. Temperature accuracy is specified as ±1.0°C for temperature-only models and ±0.5°C for combined temperature/humidity models; humidity accuracy is listed at ±5%RH where applicable. Each unit provides a record capacity of 43,000 data points.

Power is supplied by a 1/2AA 3.6V Li battery, supporting up to 12 months of operation. The device includes LED indicators for temperature and humidity limit alarms and displays current values alongside maximum/minimum readings via the OK key interface.

Variance in Measurement Capability

• OM-HL-SP-T: Measures -30~70°C with ±1.0°C accuracy; no humidity measurement capability.
• OM-HL-SP-TH: Measures -30~70°C (±0.5°C) and 0~100%RH (±5%RH).

Configuration Options

The OM-HL-SP Series is offered in two primary configurations to address specific monitoring needs:

• Sensor Types: Temperature-only or combined temperature and humidity.
• Housing & Protection: Pen-size form factor with IP67 enclosure rating (waterproof and dustproof).
• Data Interface: USB connection port for data transfer to a PC.
• Display Features: Simultaneous display of temperature, humidity (where applicable), battery status, max/min values, and upper/lower limits.

The series includes mounting brackets and screws as standard accessories. The device dimensions are 125 L x 28 W x 22 Dia mm.

Model Number Guide

• OM-HL-SP-T: Temperature-only variant.
• OM-HL-SP-TH: Combined temperature and humidity variant.

The series carries CE approval certification. The unit contains no user-serviceable parts; attempting repair or service may void the warranty.

Key Product Differences

The OM-HL-SP series is offered in two pen-size USB data logger models, chosen by the measurement configuration required:

• OM-HL-SP-T — temperature-only data logger with display.
• OM-HL-SP-TH — combined temperature and relative humidity data logger with display.

Both variants share the same pen-size form factor, on-board display, and USB data transfer to a PC, and ship with mounting brackets and screws as standard accessories.
