NEW FEATURES OF THE M-BASIC II
Excellent Agreement with other M-BASIC II Analyzers: One of the design priorities of theM-BASIC II was to improve the “analyzer to analyzer” agreement within the M-BASIC II family and over indefinite periods. The results are an inter-instrument correlation of 0.30% andlong-term correlation of 0.50%. This is an order of magnitude improvement over previous MBASIC roast analyzers. A high level of inter-instrument agreement and confidence can be maintained even with analyzers in remote locations.

No More Fragile Glass Sample Dishes: The M-BASIC II joins the E20CP Roast Analyzer as a top-viewing instrument. It uses resilient plastic dishes, replacing the fragile glass type required by the bottom-viewing models. No sample dish cleaning is required from sample-to-sample tests.

Simplified Calibration: A two-point calibration method improves long-term control over both the analytical slope and span. In addition, improved stability requires less frequent calibration and takes only about one minute.

Super Durable Calibration Standards: The M-BASIC II features a new two-sided single calibration disk. Made from high strength plastic, this disk withstands the industrial environment, is stabilized for long-term accuracy, and can be easily cleaned without damage.

Enclosed Shielded Sample: The sample is placed in a drawer that shields the product from ambient light during analysis eliminating potential environmental influence.

Improved Linearity: The M-BASIC II uses the same chemistry based analysis strategy as all previous Agtron Roast Analyzers but roast scores now correlate more exactly to the sensory assessment of roast development. The M-Basic II has a correlation to the related compounds of 1.0%. The M-Basic that it replaces had a 3.0% correlation.

Improved Resolution: The M-BASIC II has a system resolution of 0.10%; extreme accuracy is inherent.

Faster Warm-up: The M-Basic II will take accurate readings 30 minutes after the analyzer is turned on. The previous M-BASIC’s required a 24-hour warm-up before use.

Solid State Long Life Lamps: The M-Basic II uses substrate-based solid-state NIR illumination eliminating the need to replace lamps. This new illumination features electronic regulation. As a result, the analyzer is extremely stable and impervious to line voltage fluctuation and transients. The design MTBF of the light source is 80,000 hours. When and if the light source does need replacement, it can be done easily in the field.

Super-Regulated Power Supply: The M-BASIC II has an all-new power supply. Electronic regulation allows the analyzer to function normally and accurately even in “brown-out” power line conditions. As an example, the 120VAC/ 60Hz version of the M-BASIC II will operate within specification at line voltages as low as 100V or as high as 140V and frequencies from 48 to 68Hz. The analyzer is also well isolated and protected from the types of line voltage transients common to industrial environments that can cause damage to sensitive electronics.

Lower Power Consumption: The M-BASIC II uses about 28 watts, one-third the power of
previous models.
