The AVI (Analog Voltage Input) is an intelligent instrument that uses its built-in processor to monitor voltages and compare them to high and low limits.
This approach reduces the software load on the external computer and enables high-speed voltage monitoring and fault detection.
- The failures (outside the limits) are detected by the AVI tool and the notification is sent to the host PC. (Also recorded by the included TestTRAK software)
- All 32 channels are independent and each is capable of detecting boundary faults down to 500 nS (no mux scan).
- Measurements can be recorded at programmable rates (using TestTrak).
- The built-in system monitor keeps track of instrument temperatures and voltages.
- The instrument includes 16 channels of digital outputs (TTL) that can be used to synchronize events with other instruments or generate clocks to be used for timing (timing controlled by user-programmable profiles).
- The instrument includes 2 channels of programmable voltage output (DAC) (can be used to control external power supply or other uses).
- The user simply sets the parameters for each channel using the included TestTrak software, assigns the profile, and starts the instrument.
- All voltage readings are true RMS regardless of waveform.
- Ethernet interface (integrated web server)
AVI Specifications
Number of channels : 32 (Single Ended or Differential)
Maximum conversion rate : 2M samples/sec (500nS)
Voltage ranges : +/- 2
Volts (higher voltage adapters available)
Analog to Digital Converter (ADC) : 12 bit (4096 steps) (Resolution: 0.976 mV)
Gain : X1, X10
Input protection : over temperature and over voltage
Input impedance : 100K ohm
16-channel programmable digital outputs : TTL; 1MHz maximum; each 8k deep memory for waveform generation.
2-channel programmable DAC output : 450mA; +/- 12V DC
Frequency Counter : Each channel monitors frequency and voltage (20Hz-100KHz).
The AVIO (Analog Voltage Input/Output) instrument has 16 channels, each configurable for input or output.
An AVIO card can replace many instruments (such as multimeters, oscilloscopes, frequency meters and generators)
Each channel can provide or monitor time-varying AC or DC signals (sine, triangle, square waves and more)
Other cards similar to AVIO have only one analog-to-digital converter for all channels on the card. AVIO is a cheaper and faster solution because each channel has its own dedicated analog-to-digital converter. This allows for faster sampling rates and independent channels (no muxing)
All voltage readings are true RMS regardless of waveform.
Input sampling rate up to 1.1 MS/s (mega samples per second) and output rate up to 1 MS/s
Ability to drive currents up to 450 mA per channel
The output channels monitor the current.
The input channels monitor frequency and voltage.
The inputs can handle voltages between +/- 170 volts (so 120 volt outlets will not damage the module)
Ethernet interface (integrated web server)
The included TestTrak software allows for easy use without programming

The GASPIRA Original Galli Fume Extraction Hoods are hoods specifically designed and manufactured to extract fumes and odors from processes that normally occur in laboratories. The GASPIRA model is ideal for ovens and stoves.
The device allows you to quickly and easily separate light and heavy seeds.
Ideal for cleaning and characterization activities of CWR (Crop Wild Relatives) at plant germplasm banks.
The seeds are placed inside a drawer in the acrylic glass cylinder.
A fine mesh filter closes the top of the cylinder.
A speed-controlled fan generates a constant flow of air upwards inside the cylinder.
The seeds, depending on their size and weight, fall into one of the three collection containers located on the sides of the cylinder.
This way the lighter seeds will fall into the upper container, while the heavier ones will fall into the lower one.
An additional filter at the bottom of the cylinder prevents seeds from entering the fan.
When the appliance is turned off, the filter will contain a deposit consisting of residues and any small stones.
The collection containers are equipped with a fastening system that allows for easy release.
Dimensions: 440x220x1045
Weight: 7.5 kg
Power supply: 230v 50Hz
Version with LCD display with centesimal resolution, with EXTERNAL temperature sensor (to be ordered separately) Universal DataLogger with External Sensor FOR Ultra-Freezers, Dry Ice, refrigerators, freezers, warehouses, transport, incubators, stoves and ovens
