For inquiries about our products, please use the inquiry form.
PACKKEEPER is low-cost model for O2 measurement only
PACKMASTER is DO-compatible model by using option
PACKLEADER is O2 & CO2 simultaneously measure with one unit
■ One-touch measurements
Just press the START key to begin.
The automatic stability decision function will display the stable value.
Suppose the oxygen sensor fails and becomes unusable within one year of opening the package and starting use. In that case, Iijima Electronics will provide a "fault replacement" so you do not have to purchase an additional sensor for one year. The "fault replacement" is not a new sensor but a product that can be used for the remainder of the warranty term.
Easy on-the-spot replacement
1. Pull the oxygen sensor out from the probe.
2. Insert the new oxygen sensor.
3. Mount the probe onto the housing to complete the replacement.
Convenient functions
■Clogging detection function
A pressure sensor is mounted. A message will appear if the needle or tube is clogged when the gas is drawn. Replace the part at the site to resolve the problem.
■Guidance display function
Easy-to-understand troubleshooting and error messages are displayed in Japanese. QR Codes are also provided so you can check detailed procedures and videos on our website.
■Memory function (300 cases)
Press the MEMORY key to record the measured values. The history can be read out easily.
