Product Details

Class I NTEP Approved Legal For Trade The National Conference on Weights and Measures certifies the SJ-620 Legal for Trade with Certificate of Conformance number 05-063A2. You can count on getting accurate readings time after time.

Vibra® Tuning Fork Sensor The tuning fork sensor in this NTEP approved centigram balance is extremely stable and minimally affected by temperature. The SJ-620 delivers maximum performance within minutes of start up, while balances with traditional strain gauge and electromagnetic load cells need up to an hour to warm up before use. The tuning fork sensor is also more resistant to shock than other load cell types leaving you with a balance that is engineered for durability, accuracy and longevity.

RS-232 Interface The SJ-620 has an RS232 communication port built right in for easy communication with printers, computers, monitors and more.

Does This Thing Count? You bet it does! All ya need to do is weigh a sample amount of pieces, so the SJ620 can know how much each piece weighs, then start counting. You'll be finished in no time.

Weighing Hook Sometimes the thing ya need to weigh just won't fit on the weighing platform. Now that's a problem for most balances, but not the SJ. This precision balance has a weighing hook built right into the bottom. This hook works by pulling on the weighing platform when an item is hanging from it, just like if ya were to put an item on top of the platform. This will come in handy for density determination, gravity calculation, and a lot more.

Tare Feature The tare button on this centigram balance can be pressed to "zero out" the weight that is on the platform. You can then add more weight and the balance will only display the weights of the items you're adding...this sure is useful.

Liquid Level Indicator & Adjustable Feet This very handy feature helps you quickly and easily get your balance nice and level. All ya have to do is adjust the feet on the bottom of the SJ-620 until the spirit bubble is centered within the level indicator. A level precision balance is important for getting the most accurate weight readings.

Sealed Keypad You won't have to worry about dust and dirt getting stuck under and around the buttons on this precision balance... The PB6200 has an easy to clean sealed keypad.

Easy Calibration You'll have no problem at all calibrating this precision balance. You'll just need to pick up the proper calibration weight to get the job done.

Stainless Steel Platform The SJ-620-NT NTEP approved balance has a durable stainless steel weighing platform that doesn't scratch easily and will keep its shine without rusting or tarnishing.

1 YEAR MANUFACTURER'S WARRANTY! Intelligent Weighing Technology warrants this NTEP balance free from defects in material and workmanship for the first year from the date of shipment.

High quality product
This is easily the nicest scale I’ve ever had. It has the specs needed for licensing for my business. The fda inspectors complimented it and was able to get it calibrated easily. Thanks for the great product and service. Highly recommended.
