Mercer indicators, marketed for the UK, are available in the US as well. Made in Switzerland, these are among the best inch-reading as well as metric dial test indicators available. They're rarely in stock, but can be had in about 3 weeks. We present here the most popular models, but please don't hesitate to contact us regarding any indicator with the Mercer name. Mercer test indicators have several models with ranges and configurations which are unique among all test indicators (see chart below). One caveat: the old-style Mercer indicators were made in England. These are no longer available, but you can substitute the new models with confidence. All new models carry the suffix -1 on the model number. They're a big improvement over the old ones. Mercer indicators which are metric will have yellow dials. This is the norm for the US and UK. Inch reading indicators will have standard white dials. The Series 300 indicators come with a 1/4" mounting stem in a hard plastic box. Other size stems and attachments are available on page page 36. A serial number and declaration of conformity are included, but without calibration data.
