Pen and plotter pens Ribbon cassette

Bringing You the Highest Reliability

Servo Unit


The pen servo unit takes advantage of an ultra-small, rack-and-pinion stepping motor. The servo unit is smaller and consumes less power than previous models.

Splash-proof Front Door (conforms to DIN 40050-IP54)


The front door meets DIN 40050-IP54 standards in panel-mount installations.

High-Voltage Solid State Scanners

High withstand voltage semiconductor relays have been adopted for scanners that switch the input signal. They enable high speed scanning of six dots per second, increase the life of the scanner, and reduce noise.

Use of ASICs

The recorders feature a high degree of functional integration through Yokogawa's renowned ASICs (application specific integrated circuits, or custom ICs). They allow for reduced power consumption, increased lifespan of components, and suppressing of heat emmisions.

Safety/EMC Standards

EMI testing LAB in Yokogawa

Yokogawa's highly reliable industrial recorders support safety and EMC (electromagnetic compatibility) standards. And of course, the µR conforms to the European CE marking standard.

This µR reflects advances in the chart cassette and internal illumination. Also, our new disposable pen (pen model), plotter pen, cassette ribbon (dot model), and chart paper maintain compatibility with previous models.

By using a high intensity white LED and light-diffusing rod for the internal illumination, the visibility of the chart section has been greatly increased.

Chart Cassette

The chart cassette is equipped with a chart-ejection function. You can write memos on the chart and check the historical trend during recording.

Basic operation

  • When you start recording, the Start printout is performed.
  • When you stop recording, the End printout is performed.
  • During analog recording, you can print out messages that include measured* values.

This basic operation pattern is shown in the figure below.

By using the computation function of the SMARTDAC+ series Paperless recorder GX/GP, computation option computes the "F-value," or sterilizing value for the sterilization process, so that the computation results can be recorded in the form of data.

The µR series can be used close together. There is no specified spacing. However please see the panel cutout dimensions for each model in the specifications.
It conforms to the DIN40050-IP54 dust and splash proof specification.
The length of the chart paper is 16 m (16000 mm). One month is 720 hours, therefore if you set a chart speed of 16000/720 = 22 mm/hr or less, you can record for a month. Pen model: From 5 mm/hr —12000 mm/hr, select 20 mm/h. Dot model: In th...
