  • Thông số kỹ thuật
  • Đồng bộ tiêu chuẩn
  • ·         Resolution: 1 mm2 (1 mm x 1 mm scanning area).
  • ·         Accuracy: Within ± 2% for samples >50 cm2.
  • ·         Display Capacity: Area: 9,999,999.99 cm2, Length: 99,999,999.9 cm, Width: 12.8 cm.
  • ·         Display: 2 line x 16 character LCD.
  • ·         Keyboard: Sealed, 24 key tactile response with audio feedback.
  • ·         Real Time Clock: Year, month, day, hour, minute, second. Accuracy: ± 3 minutes per month (0 to 55 °C).
  • ·         Internal Memory: More than 2.1MB of non-volatile FLASH. Measurement data is maintained even in absence of power.
  • ·         Memory Capacity: From 65,000 to 125,000 individual leaf area measurements.
  • ·         Communications: USB 1.1 Compliant, Full Speed, Bus rate @ 12 Mbps; RS-232 DTE, N,8,1, Baud rate set @ 38400 bps, Hardware Flow Control.
  • ·         Sample DimensionsWidth: 127 mm maximum, 1 mm minimum. Thickness: 8 mm maximum. Length: 1 meter maximum.
  • ·         Scanning Speed: Up to 1 m/s. Length encoding cord drawing speed need not be constant. Error message indicates if encoding cord is drawn too fast.
  • ·         Power Requirement: Rechargeable 6V lead-acid battery; or 115/230VAC, 50/60 Hz, 20W maximum.
  • ·         Battery Capacity: Typically 12-15 hours of continuous operation.
  • ·         Recharging Time: 5-8 hours, instrument off. Charging circuitry is built in.
  • ·         Battery Voltage Sensor: Low battery warning occurs approximately 1 hour before automatically shutting off the instrument. Over-voltage warning occurs if battery becomes over-charged.
  • ·         Scanning Head: LED Light Source: 6.4 mm from outer edge. Size: 30.5 cm overall length (12.0"). Weight: 680 g (1.5 lb.)
  • ·         Operating Temperature: 0 to 55° C, 0 to 95% RH (noncondensing).
  • ·         Storage Temperature: -20 to 55° C, 0 to 95% RH (noncondensing). Long term storage at high temperatures will shorten life of internal battery.
