Moving the HOBO ZW Database from One Computer to Another

To move or copy your HOBO ZW Datanode database from one computer to another, you will need to copy a folder called "COSMOS" and all of its contents to a specifc location on the new computer. Copy...

HOBO MX2501 User-Replaceable Electrode Info

With gel electrolyte and double Pellon® junctions minimizing the chance of contamination of the reference electrolyte, the user-replaceable, plastic-bodied pH electrode for the HOBO MX2501 pH logger...

ZW (Zigbee 802.15.4) Radio Channels vs WiFi (802.11)

Attached is a drawing that depicts IEEE802.11 (WiFi) radio channels vs IEEE802.15.4 radio channels

Cleaning Optic StowAway/StowAway TidbiT data loggers

Do not use any type of chemical on an Optic or TidbiT data logger! You can wash the data logger with a mild soap and warm water solution. If the data logger has a mineral or algae build-up that will...

pH Data Logger Best Practices

Understanding the effects of pH changes over time in aquatic environments is essential to climate change research, compliance monitoring, and environmental projects. This webinar covers best...

Wiring Diagram - Monitoring Three-phase Energy using the ZW Wireless Data Node and the Wattnode kWh Transducer

Attached is a wiring diagram that shows how to connect a Wattnode kWh Transducer to a HOBO ZW-008 or ZW-005 wireless data node to log energy consumption on a 3-phase circuit. Note: The wiring from...

A quick temp-accuracy check (ice bath)

We receive many calls requesting information on how to calibrate our data loggers. While our data loggers cannot be calibrated, you can certainly check to see if the data loggers are recording within...

Remote Water Level Monitoring Application (U30)

The combination of the HOBO Remote Monitoring System/GSM and one or two third-party water level sensors with 4-20mA analog outputs provide a solution to remotely monitor water levels and access data...

Can the HOBO MX2501 pH Logger be Used with the Total Hydrogen Scale (pHT)?

The Total Hydrogen Scale (pHT) requires custom buffers that are designed to mimic the activity of hydrogen ions in seawater. Because of this, the HOBO MX2501 logger cannot be used to calibrate to the...

Totalizing RG3 Rainfall Data

A common question when working with rain data is: How much rain per “time interval?” That could be a day, a week, a month, or whatever you are looking for. The RG3 logger collects rain events as...
