# Data Logger, 10 to 1100hPa, Pressure, Temperature & Humidity ![Product image](https://novapart.co/image/farnell:3907354/) **URL**: https://novapart.co/products/OMYL-RH23E/data-logger-10-to-1100hpa-pressure-temperature **SKU**: OMYL-RH23E **Manufacturer**: OMEGA **Price**: €575.0500 **Stock**: 10+ **Lead Time**: 281 days (indicative) ## Specifications | Parameter | Value | |---|---| | Svhc | Lead (04-Feb-2026) | | Product Range | - | | Data Logger Type | Pressure, Temperature & Humidity | ## Datasheet 📄 [Download PDF](https://novapart.co/datasheet/farnell:3907354/) ## _**Temperature, Humidity and Barometric Pressure Data Loggers**_ ## **OMYL-RH23 and OMYL-RH23E** - U **Integral Temperature/Humidity/Pressure Sensors** - U **OMYL-RH23 Has Internal Temperature/Humidity/ Pressure Sensors** - U **OMYL-RH23E Has Internal Pressure Sensor with Temperature/Humidity Sensors Fitted in Integral Probe** - U **Up to 4 Million Readings (Internal Memory Size)** - U **Up to 4 Hz Sampling Rate** - U **High Accuracy** - U **20 Bit A/D Converter** - U **Shock Proof, IP65 Housing (Dust and Water Jet Proof)** - U **Transfer Rate of 500 kbps** - U **Low Current Consumption** - U **Up to 4 Years Battery Life** The OMYL-RH23 and OMYL-RH23E are robust devices capable of logging temperature, humidity and barometric pressure readings and are software configurable to record either all three of these parameters or just individual variables. These data loggers are available with standard memory of 100,000 readings (OMYL-RH23, OMYL-RH23E) or expanded memory of 4 million readings (OMYL-RH23-4M, OMYL-RH23E-4M). The OMYL-RH23/OMYL-RH23-4M have built-in sensors for temperature, humidity and barometric pressure. The OMYL-RH23E/OMYL-RH23E-4M have an internal pressure sensor with the temperature/ humidity sensors fitted in an integral 100 mm (3.94") steel probe. These data loggers are suited for a variety of applications including environmental or climate studies, meteorological research and also in clean rooms and laboratories. The storage medium is non-volatile flash memory so no data is lost if the battery becomes discharged. Data logger setup as well as data retrieval is accomplished using the included standard OMYL-SOFT software. Downloaded data is stored in the OMYL-SOFT software as a text file for viewing in third party software packages or Microsoft Excel. The OMYL-SOFT standard software does not include any graphing functionality. Graphing and analyzing downloaded data files requires the OMYL-SOFT-PLUS version of the software (sold separately). **OMYL-RH23 shown larger than actual size.** **Temperature Range:** -30 to 70°C (-22 to 158°F) with standard lithium battery (included); -40 to 90°C (-40 to 194°F) with optional high temperature lithium battery **Resolution:** 0.01°C (0.02°F) **Accuracy:** See chart below **Humidity Range:** 0 to 100% RH **Resolution:** 0.01% RH **Accuracy:** See chart below ## **SPECIFICATIONS** ## **Sensor Type** - **OMYL-RH23/OMYL-RH23-4M:** Internal temperature, humidity and pressure sensors - **OMYL-RH23E/OMYL-RH23E-4M:** Internal pressure sensor with temperature and humidity sensors fitted in integral probe **1** **To Order, Call** **or Shop Online at** _**omega.com[SM]**_ **OMYL-RH23E shown smaller than actual size.** ## **Barometric Pressure** **OMYL-SOFT-PLUS graphical display.** **Range:** 10 to 1100 hPa **Resolution:** 0.1 hPa **Absolute Accuracy @25°C:** ±1.5 hPa **Relative Accuracy @25°C:** ±0.5 hPa **Reading Rate:** 1 second to 24 hours; 2 Hz, 4 Hz in fast mode **Start Modes:** Immediate start, delayed start ## **Memory Capacity** **OMYL-RH23, OMYL-RH23E:** 100,000 readings - **OMYL-RH23-4M, OMYL-RH23E-4M:** 4 million readings **Memory Wrap Around:** Yes (software configurable) **Battery:** 3V lithium battery [standard temperature range battery (included) optional high temperature range battery]; user replaceable **Battery Life (Standard Temperature Range Battery):** 4 years at 1 minute reading rate, 230 days at 10 second reading rate, 25 days at 1 second reading rate **LED Functionality:** Integrated status LED indicates data logging status, low battery or alarm condition **Alarms:** Software programmable high/low thresholds **Computer Interface:** USB (interface cable included) **Software:** XP SP3/Vista/7 and 8 (32- and 64-bit) **Operating Environment:** -30 to 70°C (-22 to 158°F) with standard lithium battery; -40 to 90°C (-40 to 194°F) with optional high temperature lithium battery ## **Dimensions** - **OMYL-RH23, OMYL-RH23-4M:** 30 H x 50 dia mm (1.18 x 1.97") **OMYL-RH23E, OMYL-RH23E-4M:** 30 H x 50 dia mm (1.18 x 1.97") with 100 L x 8 dia mm probe (3.94 x 0.31") **Weight** : 70 g (2.5 oz) **Enclosure:** Robust, shock-proof POM, IP65 |**To Order**|**To Order**| |---|---| |**Model No.**|**Description**| |**OMYL-RH23**|Temperature, humidityand barometricpressure data logger with internal sensors, 100,000 readings| |**OMYL-RH23-4M**|Temperature, humidityand barometricpressure data logger with internal sensors, 4 million readings| |**OMYL-RH23E**|Temperature, humidity and barometric pressure data logger with internal pressure sensor and integral
