It covers a 1–500 g range (centiNewton, cN, is the standard calibration unit; gram calibration is available as an option) and uses a strain‑gauge bridge for precise readings that can be viewed or captured via multiple outputs. The meter offers NORMAL and DAMPED measuring modes, a HOLD function, and PEAK mode to retain peak readings, with a three‑roller head that can use ceramic pins for high‑speed filament runs up to 5000 m\/min. A long‑life 9‑V lithium battery (included) powers the device for roughly 100 hours of typical use, and the complete outfit ships in a foam‑fitted carrying case with the meter, battery, and instruction manual. Key specs include a maximum sensing‑roller displacement of 0.5 mm, minimum access space of 3\/4\" × 1\" (20 × 26 mm), operating temperature range of 40–115°F (5–45°C), and relative humidity limit of 95%, with thermal drift at 0.25% of full scale per degree C and an automatic zero at ±20% of range. The unit provides analog 0–22 V DC output for recorders, a digital parallel printer interface, and optional remote display, with a 100 Hz scanning rate (40 Hz in PEAK mode) and a natural frequency of 250 Hz for responsive, stable readings. The ETMP‑500 is the “with pins” variant of the ETM family, designed for precise tension checks in limited‑access installations. \u003c\/p\u003e\u003c\/div\u003e","brand":"CHECKLINE","offers":[{"title":"Used Surplus - Excellent Condition","offer_id":51677980459310,"sku":null,"price":593.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0940\/0818\/1038\/files\/Ebay_website_image_77c52e55-03cc-466d-ba97-c7c1ac3523a3.jpg?v=1769570268","url":"https:\/\/plgautomation.com\/products\/check-line-instruments-etmp-500-tension-meter","provider":"PLG Automation ","version":"1.0","type":"link"}
