A chromel-alumel thermocouple was placed very close to the sample and was connected to a digital microvoltmeter
(Keithley 197A, Keithley Instruments), in order to measure the sample temperature accurately.
1]) was measured on four dates from the 26th day after emergence (DAE) (26, 39, 47, and 53 DAE) using a linear sensor (LI-191 Quantum Line Sensor) connected to a microvoltmeter
(both Lambda Instruments Corporation LI).
Produced voltage was registered by means of the microvoltmeter
w]) was measured with four replicates in situ with a leaf psychrometer attached to a microvoltmeter
(L-51 and HR-33T; Wescor Inc.
Water potential of soil from turtle nests at field water content was measured with a stainless steel psychrometer (Wescor, PST-55, Logan, Utah, USA) and dew-point microvoltmeter
(Wescor, HR-33T, Logan, Utah, USA) coupled to a MacLab data acquisition system.
records the seemingly random, mixed signals that are known in the trade as electrochemical noise.
Kiethley 6221 setup was used and the voltage drop between the two probes with a span of 2 mm was measured by a microvoltmeter
(DMV-001) at 25[degrees]C.
Logan, UT) and read with a psychrometer microvoltmeter
Merrill, Logan, UT) were connected to a Wescor microvoltmeter
Measurements of water potential ([Psi]) and solute potential ([Psi]s) of the same terminal leaflets of mainstem leaves in the upper canopy were conducted at approximately 0830 h using dewpoint thermocouple psychrometers attached to a Wescor HR 33-T dewpoint microvoltmeter
