Overview
The Defelsko PosiTector SHDA1 Shore Shore Durometer is a Handheld instrument designed for the measurement of Crowd Hardness in Non-metallic materials. This model is suitable for the Shore A Hardness range and features user-adjustable Measurement time, Auto Ignore mode, and resistance to solvents, acids, oils, water, and dust. It supports USB, WiFi, and Bluetooth connectivity and includes a calibrate certificate traceable to NIST.
Features
1. Simple: Enhanced one-handed menu operation, including Chinese interface; user-defined test time, screen countdown display; reset function can quickly restore to factory state
2. Durable: acid-proof, oil-proof, waterproof, solvent-proof, dust-proof; anti-collision rubber protective cover with waist clip
3. Accurate: Each instrument has a calibrated certificate that can be traced back to NIST standards; Auto-filtrate mode filters less than 20% and more than 90% of readings according to international standards; High resolution mode, Screen Display resolution is increased to 0.1; Random measurement test blocks are provided; ISO and ASTM standards are met
4. Universal: can and DeFelsko Ultrasonic Thickness Gauge, Coating thickness gauge, dew point instrument, salt measurement instrument, surface roughness instrument, Pap hardness gauge shared host; high contrast ratio reversible color display, with backlight; inverted display, convenient reading; use alkaline battery, optional rechargeable battery
5. Effective: continuous display including average, Standard Deviation, Maximum/MIN Minimum and measurement times; upper and lower limit alarm; screenshot function, can save the screen display into picture format; connect to the computer conveniently through the USB data cable, and power to the host; can download and browse the data of the host through the computer; can upgrade the host program through the computer
Principle
The hardness gauge works on the principle of Crowd Hardness and determines its Shore Hardness value by measuring the Crowd depth of Non-metallic materials under a specific pressure. The instrument uses an automatic ignore mode to ensure readings meet international standards and a high resolution mode to improve Measurement accuracy.
Applications
Soft plastic, soft rubber, neoprene, silicone rubber, etc
Standards
ASTM D2240、ISO 868/7267/7619、DIN 53505
Steps
1. Turn on the power supply of the instrument and select the Chinese interface
2. Set the user-defined test time and observe the screen countdown
3. Probe placed on the surface of the material to be tested for measurement
4. The instrument automatically filtrates invalid readings and displays the results
5. Use the reset function to restore the factory settings.
6. Connect the computer via USB for data transfer or program upgrade
Notice
• Ensure instruments are calibrated and up to standard before measurement
• Avoid use in extreme environment conditions to prevent affecting accuracy
• Probe cleaned after use to prevent solvent or acid corrosion
• Replace the battery in time when the battery is low, it is recommended to use alkaline batteries
When storing data, be careful to limit it to 250 readings to avoid overflow
Make sure the USB cable is secure when connecting to the computer to prevent data loss
