This single unit solves all the problems you have with power checking at your worksite!

You can rely on it for your energy saving activity.

Many of the currently used power meters are not suitable for easily measuring power of a variety of machines and distribution boards. As a result, the electric power of a great number of machines in worksites is left unmeasured.
Our Portable Power Monitor ZN-CTX21 solves such problems. It is the industry's first "portable power monitor for energy-saving activities at the worksite."
It is "usable for anyone" "with ease" and indicates measurements "on site" immediately.
This new concept-based Portable Power Monitor ZN-CTX21 will make a great contribution to energy-saving activities at the worksite.

Five Types of Dedicated CT units for Various Applications

Clamp type CT is added to the lineup.

Four types of split type CTs and a clamp type CT (200A) configure the lineup.
The clamp type CT provides easy measurement in locations that are difficult for CTs of other types.

Power Consumption Checkup covers Devices to Distribution Boards

Changing the number of CTs connected to the branch cable enables measurement of single-phase 3-wire, three-phase 3-wire (unbalanced voltages in three-phase system) and three-phase 4-wire, too.

Checkup at the Time and Behavior to Watch Out for

Display of cumulative electric power (equivalent value)

When logging is started, the upper space displays the time and the lower space displays cumulative electric power (equivalent value). In this way, you can check electric power used from the start to the end of logging.You can set the logging conditions not only from the buttons but also by specifying the starting time or elapsed time.

Standby Electricity is also not Overlooked

Automatic range selection function

Our product is capable of measuring minute electric current that has been immeasurable by existing models. This feature enables you to check electricity consumption of a machine on standby.

*1. In high-speed logging mode, data is recorded in 83 ms at 60 Hz and in 100 ms at 50 Hz.
*2. Momentary power and integrated power values are converted from the measured current. Correctly specify the
number of used channels, applicable measurement target circuit, CT type, frequency, voltage and power factor.
*3. The display turns OFF after 10 seconds of no user operation and recovers by a key operation when SLEEP mode is
specified. LAN cannot be used when sleep mode is specified.
*4. Automatically writes the data to the SD memory card when the internal memory reaches its capacity and continues
recording until the SD card memory capacity reaches its limit. The unit stops operation if there is no SD memory
card inserted when the internal memory reaches its capacity.
(Recording can be resumed after inserting an SD memory card and outputting the data to it at a press of button.)
*5. Continues the recording of the latest measured values until the internal memory reaches its capacity. (If the internal
memory capacity exceeds the capacity, data is overwritten from the oldest one in the memory.)
*6. Output when the integrated power upper limit specified in THR mode is exceeded. An alarm output is not available in
SLEEP mode.
*7. An OMRON HMC-SD291 SD Memory Card or an SDHC Class 4 or higher memory card is recommended.
*8. Nickel-metal hydride cells or alkaline dry cells can be used. Manganese battery cells cannot be used.
*9. Battery life varies depending on the measurement environment, recording interval, operation mode as well as the
battery type and performance.
*10. Conditions: Two AAA nickel-metal hydride cells; Sleep mode; Continue mode; Recording interval: 1 s; SD memory
card: HMC-SD291; Operation temperature: 23°C ; and Automatic range selection off
*11. The installation place must be free from physical shock when using mounting magnets.
*12. Already installed on the product by factory default.
