Itokii PRO Wireless 0-500V Voltage Meter - commercial AA battery powered.

SKU: ITS2-9-W2-VM-500

The Itokii PRO 0–500 VAC voltage meter is an easy-to-deploy wireless interface for measuring voltage.Within 15 minutes, this sensor can be mounted, connected to a machine, and configured. The meter then monitors potential differences between two electrical points at user-determined intervals. If it detects voltages that have fallen below or risen above user-set thresholds, the user is alerted via email, text, or call.


This sensor measure the voltage of an AC power system in volts alternating current (VAC) Root Mean Square (RMS) on user-specified intervals. The meter can measure up to 500 VAC RMS. Key Features - Measures voltage up to 500 VAC RMS - Resolution: 0.1 VAC RMS - Accuracy: - Uncalibrated: ± (1 Volt + 2% of reading) - Calibrated: ± (0.5 Volt + 1% of reading) - Configurable thresholds for critical condition monitoring

Example Applications - Power Lines - Machinery - Electrical Motors - Generators


WARNING: Use caution when interfacing to the Wireless Voltage Meter. Negative voltages,AC Voltages, or DC Voltage exceeding 600VWILL DAMAGE the electronics of the Monnit Wireless Sensor. Monnit is not responsible for troubleshooting, replacing or reimbursing damages incurred by disregarding this warning.


    • PRO - Leading Enterprise Grade "Internet of Things" Solutions

      PRO sensors offer 3 to 4 times the range of standard sensor platforms, extending non-line-of-sight reach to an exceptional 1,000+ feet through walls (12-14 walls typical). Using Frequency-hopping Spread Spectrum (FHSS) also allows PRO sensors to have better interference immunity from other wireless devices.

      Superior power management provides PRO sensors with almost twice the battery life of Itokii’s standard wireless sensors.

    • Coin cell sensors typically last 3+ years.
    • AA and Industrial sensors typically last up to 10+ years.
    • PRO products employ  new Encrypt-RF™ Security (256-bit Diffie Hellman key exchange and AES-128 CBC encryption for all sensor data messages), so security is maintained at all communication points from sensor to gateway, gateway to software, then back again.


      Integrated on-board data storage allows PRO sensors to store data messages if communication to a wireless gateway is disrupted (power outage, Internet outage, or out of range). Messages that can’t be delivered will be time-stamped and stored in memory (up to the last 512 messages) until communication with the gateway is restored, at which point the messages will all be transmitted.

      Over-the-air updates allow PRO products to be updated remotely if new fixes or features become available.

      Itokii PRO Industrial Sensors come in an IP65, NEMA 4X, CE rated, sealed, and weatherproof enclosure. They are powered by a single, replaceable, Industrial grade 3.6 V battery (included).

      An optional solar powered version is also available. The solar powered version includes a Lithium Iron Phosphate rechargeable battery in conjunction with a solar power cell to keep the battery charged and at optimal capacity. If there is no light present at the solar cell, the battery alone could continue to power the sensor for up to 8-10 years.
