MMS competitive comparison

MMS COMPETITIVE COMPARISON

Navas Instruments policy is to constantly improve and upgrade TGA and MMS software and hardware (patents) for customer- specific needs.

Navas Instruments MMS's are designed for CUSTOMER INDEPENDENCE, AND INEXPENSIVE OWNERSHIP. It is not our policy to charge customers high prices on parts or service but to have a satisfied customer base. Navas Instruments parts are standard, brand name digital precision balances, temperature controllers and standard frames. All standard components do not need a highly-trained technician to be repaired.

Navas Instruments only electronics are two (2) PC boards inside PC (Navas Instruments design). The furnace has no electronics but electrical components. Replacement of boards is easy and inexpensive. Navas software takes many precautions to help detect or prevent a malfunction.

Competitor TGA

Initial weights of crucibles and samples are taken on external balance during the analysis time

Initial weights of crucibles and samples are taken from inside the furnace carousel after the furnace finishes the analysis and cools down to room temperature

Samples slow to complete analysis do not affect the analysis time of the other samples inside the furnace. As soon as a sample finishes its analysis, the sample is extracted and a new sample is placed in the open carousel position of the extracted sample (no batch mode is used, continuous mode)

Samples slow to be analyzed, affect the analysis time of the entire batch.

When all samples have finished, the analysis of a new batch may be started

No time wasted in heating and cooling the furnace as the furnace is always hot at constant temperature

Time is wasted in heating and in cooling the furnace to be able to start analysis of a new batch

Metal crucibles can be used and also ceramic crucibles as an option for analysis of some materials

Breakable ceramic crucibles, no other options

Metal balance spindle

Breakable ceramic balance spindle

Metal balance pedestal

Breakable ceramic balance pedestal

Software upgrades available

Software upgrades are not easily available

In case of power failure, only a backup power supply of 300 watts is needed
(only to support the PC)

In case of power failure, a very expensive backup power supply of 4000 watts is needed (PC and furnace)

Automatic restart after power failure

Automatic restart after power failure is not available

All mechanical, pneumatic and electrical parts are standard (very few proprietary components)

Parts are competitor specific, only replaceable by same manufacturer

No special training needed to repair.

Repairs only by expensive personnel

Complete brand name digital precision balance with display with 0.1 mg sensitivity for easy troubleshooting

No balance, just load cell and expensive to replace

Brand name temperature controller with display

No temperature controller and no display, specific controller developed by the manufacturer

Carousel rotation by stepper motor, independent of crucible positions

Pneumatic rotation one position at a time. Rotation to every position, even to empty positions
