LP-093A

This instrument belongs to the latest generation of LOIP products. During its development we were trying to involve both the most contemporary technologies and nowadays requests of our customers.

As a result, in the analyzer LOIP LP-093A, we proudly represent several new approaches and innovations in automation of flash point control. However, the apparatus features not only state- of-the-art design and high level of automation, it is also very cost-effective and economical in maintenance. The automated Pensky-Martens flash point tester LOIP LP-093A accurately determines flash point temperature of petroleum products in a full accordance to ASTM D93 A&B, ISO 2719, IP 34, GOST 6356 and other similar standards.

How do they work:

Flash point tests are simply conducted by mounting the cup filled with sample into the heating chamber and selecting a pre- or user-programmed test method. After the test start the instrument automatically heats up the sample with a required rate, and moves the igniter down into the cup according to the program sets. When performing a test, the system will display the stirring speed, actual temperature and current test status. When the system detects a flash, the instrument stops heating, shows the flash point temperature on a display and starts quick cool-down the heating chamber to prepare to the next assay. The controller manages all the instrument's functions and settings, but since units leave the factory completely calibrated and pre-configured, there is no need to adjust anything as long as one of standard preset methods is employed (ASTM D93, variants A and B or flash point quick search).

Features and benefits:

  • Fully automated microprocessor controller for precise determination of flash point
  • Large graphic LCD-display (240x128 pixels) with a back-lit to indicate all the necessary data at a glance
  • Electro-ignition device and an electronic flash detector
  • Functions for temperature and pressure sensor calibration
  • Glass-shelled Pt-100 thermo-sensor for precise response emulation of ASTM thermometer
  • Plug-and-play connection to a PC via USB-port. Detailed test report can be transmitted to a PC via USB-connection
  • Quick cool-down after a test due to enforced venting of a heating chamber by means of built-in powerful fan
  • Last 15 results are saved in memory
  • Magnetic coupling of stirring gear eliminates any possibility of wear at this traditionally quick-tearing device

Automation

  • Automatic algorithm with simultaneous controlled operation of both a heater and a fan provides very precise support of preset heating rate (tolerance not more than ±0.3 K/min)
  • Automatic to barometric pressure 101.3 kPa, upon program settings (may be disabled). Built in barometric pressure sensor 70 to 110 kPa
  • Automatic heater shut down, audible signal and test abortion for safety
    • at 30°C above the expected flash point
    • at 370°C
  • Automatic diagnostic of all analyzer functions. In case of malfunction auto-testing system gives visual and acoustical alarm and displays the causes
