• MS-96H2 Transmission Mossbauer system
• Spectrometric table-top bench with sample holder,two collimators and gamma-ray shielding.
• Fast scintillation detector with scintillation crystal,HV supply and amplifier.
• Transducer and analogue PID feedback unit (driver) spectrometric software
• Velocity generator unit
• Single channel discriminator unit
• Control and communication unit
• ±12 V DC power supply built-in.

• Mossbauer transducer features (with feedback unit)
• Velocity range up to 40 mm/s
• Non linearity of the velocity scale below 0.1% (guaranteed for typical 57Fe measurements in ±10 mm/s velocity interval)
