Mitutoyo Surface Roughness Gauges Editorial Review
The Mitutoyo 178-390 Standard Detector is designed for use with the Surftest SJ-201 and SJ-301 models. It has a depth of 6.75 inches, making it suitable for measuring deeper grooves. It is important to note that the deepest groove it can accurately measure is 10mm, although it is recommended to stay within the 9mm range for more reliable results. One potential concern is that the accessories for taking measurements are not included with the probe. This means that users will need to purchase these accessories separately in order to fully utilize the capabilities of the detector. This additional expense may be off-putting for some buyers who were expecting a complete package. It is worth mentioning that the probe is not compatible with the Surftest 402 model. If you have a Surftest 402 and are in need of a probe, you will need to look for an alternative option as the probe for the 402 is no longer available. Overall, the Mitutoyo 178-390 Standard Detector provides reliable measurements for deeper grooves. However, potential buyers should be aware of the need to purchase additional accessories and the compatibility limitations with certain models.
