Tender For The Purchase Of Scientific Equipments During The Year 2025-26, Junagadh-Gujarat

Tender For The Purchase Of Scientific Equipments During The Year 2025-26; 1. Soil Moisture, Temperature & EC Recorder  Purpose: Records and monitors soil moisture, soil temperature, and electrical conductivity (EC) simultaneously.  Application: soil monitoring, irrigation scheduling, agricultural research  Measurement Parameters:  Soil Moisture – volumetric water content  Soil Temperature – direct soil thermal measurement  EC (Electrical Conductivity) – salinity/ion concentration in soil  Recorder/Logger:  Multi-channel data logger system for simultaneous sensor recording.  Supports factory-configured sensors as per order.  Real-time monitoring and data storage.  Display & Programming:  LCD/LED alphanumeric display.  Onsite programming via keypad interface.  Accuracy: High precision (typical EC & moisture sensors ±2–3%, temp sensors ±0.5 °C).  Data Storage:  Large dataset capacity (expandable).  Export in MS Excel format.  Power Supply:  12V battery-powered (SMF type).  Charging: 220V AC option.  Operating Conditions:  Designed for outdoor industrial/agriculture field environment.  Rugged housing for long-term deployment.  Data Retrieval:  Direct computer connection (USB/data shuttle).  Optional remote data transfer.  Durability: Weatherproof and maintenance-free design. 2. Digital Soil Infiltrometer (Double Ring Soil Infiltration Recorder)  Purpose: Measures infiltration rate of water into soil using double-ring method.  Design:  Double ring structure: o Inner ring (ID = 30 cm) o Outer ring (ID = 45 cm)  Outer ring prevents lateral water movement, ensuring vertical infiltration measurement from inner ring.  Comes with hammer, driving plate, stainless steel tripod, and data logger.  Sensor: Non-contact radar water level sensor.  Display: 16 characters × 2 lines alphanumeric display  Keyboard: 4×2 membrane keypad (onsite programming).  Clock: Internal real-time clock, accuracy ±2 minutes/year with leap year compensation.  Channels: 4 (factory configured).  Performance:  Settling time < 5 sec  Repeatability: ±0.05% FS  Accuracy: ±0.1% FS  Memory: >16,000 datasets  ADC Resolution: 16+ bits.  Recording: Unattended, virtually maintenance-free.  Operating Conditions:  Temperature: –40 °C to +75 °C  Humidity: 0–95% non-condensing  Power:  12V SMF battery (locally available), optional 220V AC charging.  Data Handling:  Output format: MS Excel  Retrieval: Data shuttle (default), Optional remote data transfer.
