Dependable accuracy... 1. Levers focus weight on a calibrated spring. 2. Dial or pointer rotates as spring stretches. 3. Weight appears in window or pointer indicates weight. 4. Mechanism also used on pulse count scales. Electronic Advanced strain-gauge electronic measurement device that is more precise than the traditional, analog mechanism. Quality engineering... 1. Levers focus weight on calibrated steel beam. 2. Beam flexes as weight is applied. 3. Solid state strain-gauge measures weight. 4. Digital readout displays weight. Electronic Lithium Advanced strain-gauge electronic measurement device with addition of lifetime lithium battery is more precise that the traditional, analog mechanism. Superior technology... 1. Levers focus weight on calibrated steel beam. 2. Beam flexes as weight is applied. 3. Solid state strain-gauge measures weight. 4. Digital readout displays weight. 5. Lifetime lithium battery eliminates hassle of battery replacement. Professional The best scale in accuracy, durability, and repeatability; patented mechanism is so exact you can see your heartbeat. Professional grade accuracy... 1. Hardened steel insert reduces friction at all contact points. 2. Levers focus weight on calibrated spring. 3. As spring stretches, shock absorber protected rack rotates and turns pinion. 4. Pointer turns with pinion and indicates weight.   Thermometers > Back to Consumer > Home
