The SDX is a “Wet-Wet” device. While it is important to keep the SDX cable’s vent tube unobstructed for barometric pressure compensation, neither the pressure transducer nor internal electronics are damaged by condensation or moisture entering the vent tube. For best results, we recommend the desiccant cartridge with vent tube adapter.
Use the RS3-B Solar Radiation Shield to protect your external sensors from sunlight and rain. This shield ensures users gain more accurate measurements, due to increased airflow around sensors. And users benefit from 2.5 times faster response time to changing conditions.
The RS3-B Solar Radiation Shield works with most of Onset’s external temperature and temperature/relative humidity, including those for our award-winning HOBO Weather Station products.
For customers interested in deploying a radiation shield with Onset data logger such as a HOBO Pendant or U-Series data logger, Onset also offers two other models of solar radiation shields; the RS1 and the pre-assembled M-RSA
This bracket is required for mounting HOBO MX2301 and MX2305 loggers in either an RS1 or M-RSA solar radiation shield.
Onset offers testing and certification of HOBO data logger and sensor RH (relative humidity) accuracy using standards traceable to the U.S. National Institute of Standards & Technology (NIST). This includes single-point (50% RH @ 25C) or three-point (25, 50, 75% RH @ 25C) NIST certification. For each data logger certified, a certificate is provided showing the device’s RH and temperature accuracy vs. a NIST traceable standard. Certification is available for all currently manufactured Onset data loggers and sensors.
NOTE: The temperature value used for RH certification is fixed at 25C and verified against a NIST-traceable 200-ohm platinum RTD (resistance temperature detector). If additional temperature certification is required at temperature values other than 25C, Onset’s temperature NIST certification services must also be performed. Onset’s temperature NIST services offer certification in an oil-bath for user-selectable temperature points between -30 and 120C. If custom temperature points are desired additional cost and lead time will apply.
Onset also offers NIST temperature certification, learn more.
Frequently Asked Questions
Q: Can I request RH NIST Certification for an existing logger that I already own?
A: Yes, please fill out our technical support form for further instructions.
Q: Can I request RH NIST Certification for loggers no longer in production (like the H08 loggers)?
A: Only Onset data loggers and sensors that are currently in production are available for RH NIST Certification
Q: Does Onset RH NIST-certify data loggers made by other manufacturers?
A: No, only currently-manufactured Onset data loggers and sensors are supported.
Q: Will I get as-found data as part of this service?
A: Onset data logger products and sensors are not adjustable to correct for drift over time. If your logger or sensor is found to be within acceptable RH limits the RH test data will be included on your certification report. If your logger or sensor is found to be out of tolerance you will be contacted by Onset Technical Support with a copy of your as-found data and offer options for repair or replacement.
The lockable, vented security case provides complete enclosure protection for HOBO data loggers. It has air circulating ports on all four sides to ensure ample air circulation for proper data logger operation. Each guard has a permanently-attached, eight-tumbler type lock, and each kit is supplied with a key. Guard kits are available with two mounting base types: solid or ring. When using the ring base models, the guard can be mounted to the wall without removing the data logger.
Items included are: Clear case cover, mounting screws, solid mounting base, ring mounting base, built-in lock with one key
The external DC power cable (CABLE-RX-PWR) is used to connect a user-supplied power source to the HOBO RX3000 Monitoring Station to charge the station’s internal battery. The external power source can be an intermittent power source, such as a 6W or larger solar panel. The external power source must be able to supply 6W, but the average power used will be much less and depends on the number and type of sensors, logging interval, and the frequency of internet connections.
The HOBO U-DT-2 U30 Shuttle Data Transporter provides convenient in-field data offload and relaunch of HOBO U30-NRC systems and HOBO Weather Stations (H21-001) and Micro Stations (H21-002 only), and HOBO Energy Logger systems (H22). The U30 Shuttle's 2 x 16-character display shows current readings (for selected data loggers), and logger status.
NOTE: HOBOware Pro software required.
Conveniently offload data in the field with the HOBO U-Shuttle Data Transporter. This product also allows users to easily relaunch HOBO U-series data loggers and HOBO Weather Stations (H21-001) and Micro Stations (H21-002 only), and HOBO Energy Logger systems. View readings on a 2 x 16-character display for selected data loggers, and access logger status for all loggers. An Optic USB Base Station is required for use with optic USB data loggers.
NOTE: HOBOware Pro software required.
